Answers

Answer 1

Given:

mass of the usain is

[tex]m=94\text{ kg}[/tex]

Acceleration is given as

[tex]a=0,\text{ 2.8, 4.86, 1.12, 0.6, 0.51, 0.18 0.19, -0.18, 0}[/tex]

Required: calculate the greatest and least net forces.

Explanation:

we know the force is given as

[tex]F=ma[/tex]

where m is the mass and a is the acceleration

to calculate the greatest force

we need find the greatest acceleration in the given table that is

[tex]a=4.86\text{ m/s}^2[/tex]

plugging all the values in the above relation we get:

[tex]\begin{gathered} F=ma \\ F=94\text{ kg}\times4.86\text{ m/s}^2 \\ F=456.84\text{ N} \end{gathered}[/tex]

now, to calculate the least force we have the find the least acceleration

that is

[tex]a=0\text{ m/s}^2[/tex]

plugging all the values in the above relation, we get:

[tex]\begin{gathered} F=ma \\ F=94\text{ kg}^\times0 \\ F=0 \end{gathered}[/tex]

so least force is zero.

we can se another least force when the acceleration is negative that is

[tex]a=-0.18\text{ m/s}^2[/tex]

then force is

[tex]\begin{gathered} F=ma \\ F=94\text{ kg}\times-0.18\text{ m/s}^2 \\ F=-16.92\text{ N} \end{gathered}[/tex]

Thus. the greatest force is

[tex]\begin{equation*} 456.84\text{ N} \end{equation*}[/tex]

and least force is

[tex]-16.92\text{ N}[/tex]

Calculate the weight of the following masses, which are at the Earth's surface. For a mass of 1.5 kg, its weight is (W)=14.7N

What is weight?

Weight is a physical term that means that how much force of attraction is applied on the mass of the object. It can be measured in Newton and Dyne.

How can we calculate the weight?

To calculate the weight we are using the formula here is,

W= mg

Here we are given,

m= mass of the object on earth. = 1.5 kg

g= The force of acceleration of the object. = 9.8m/s²

We have to calculate the value of the weight = W N.

Now we put the values in the above equation, we get

W=mg

Or, W=1.5*9.8

Or, W=14.7 N

From the calculation we can say that, For a mass of 1.5 kg, its weight is (W)=14.7N

velocity differs from speed in that velocity indicates a particle's __________ of motion.

Answers

velocity differs from speed in that velocity indicates a particle's Direction of motion.

For the majority of us, speed and velocity can be a little puzzling. Speed and velocity are different in that speed just gives us an indication of how quickly an object is going, whereas velocity not only tells us an object's speed but also the direction in which it is travelling. In contrast to velocity, which is defined as a function of displacement, speed can be defined as a function of the distance travelled. A body's instantaneous velocity is its speed right now. Average velocity is defined as total displacement divided by total time and is provided by the formula v = x/t, where x is the body's total displacement and t is the time. Average speed is never greater than average velocity, and vice versa.

A satellite is 100 miles above the earth, it has a mass of 100kg. If the mass of the satellite were doubled the force of gravity of the satellite on the earth would ?

Answers

Given:

Distance of satellite from Earth = 100 miles

Mass of satellite = 100 kg

If the mass of the satellite were doubled, let's find what would happen to the force of gravity of the satellite on earth.

Apply the gravitational force formula:

[tex]F=\frac{Gm_1m_2}{r^2}[/tex]

Where:

F is the force of gravity

m is the mass.

From the formula above, we can see the force of gravity (F), is directly proportional to the mass.

Since they are directly proportional to each other, if the mass is doubled, the force of gravity will also be doubled.

Therefore, if the mass of the satellite is doubled, the force of gravity of the satellite on the earth will also be doubled.

ANSWER:

Force of gravity will be doubled when the mass of the satellite is doubled.

Answers

Kinetic energy was "lost" in this inelastic collision is 151 J

The momentum is  given as :

m₁u₁  +  m₂u₂  =  m₁v₁  +   m₂v₂

The truck and car are locked together after the collision. The truck has same final velocity :

u = (( m₁ + m₂ ) v) / m₁

u = ( (9900 + 1000 ) × 3 ) / 9900

u = 3.30 m/s

now, the change in kinetic energy is given by :

As the swings ride hits top speed, what applies centripetal force to keep the riders traveling in a circle?

Answers

When the swing moves from the lowest point up to either peak, the main force acting is momentum; and when the swing falls from either peak to its lowest point, the main force acting is gravity. If you do not pump your legs fast enough, air resistance along with gravity will keep you down.

What provides centripetal force?The centripetal force is the resultant force because the swings move in a circle. The centripetal force—the force that keeps the rider in a circle and the horizontal component of the tention force—is produced by the total of the forces acting along the x-axis.Gravity is the centripetal force that drives astronomical orbits according to Newtonian mechanics.

In statistics, the dependent variable is also called the response variable it responds to changes in another variable.

In other words, the two characteristics of the experimental design we've talked about so far are that the experiment must have at least two comparable conditions, and the researcher must match the participants to the conditions, not the participants themselves.

I need to find wfg,wnet,the acceleration of the car and how long will it take Tyler to get to the gas station

Answers

The free body diagram representing this scenario is shown below

From the information given.

mass of car = 1200kg

Recall,

weight = mg

where

m = mass

g = acceleration due to gravity = 9.8 m/s^2

Thus,

weight of car = 1200 x 9.8 = 11760 N

Normal reaction, N has same magnitude with the weight but the direction is opposite. thus,

N = 11760 N

Frictional force = N x coefficient of friction

From the information given,

coefficient of friction = 0.67

Thus,

Frictional force = 11760 x 0.67 = 7879.2 N

Net force of the car = applied force - frictional force

applied force = 1.3 x 10^4 N = 13000 N

Thus,

Net force = 13000 - 7879.2 = 5120.8N

Recall,

net force = mass x acceleration

acceleration = net force/mass = 5120.8/1200 = 4.27 m/s^2

We want to calculate the time it will take Tyler to get to the gas station. We would apply one of Newton's equation of motion which is expressed as

s = ut + 1/2at^2

where

s = distance covered

t = time

a = acceleration

u = initial velocity

From the information given,

s = 15

a = 4.27

u = 0 because the car was at rest(Since it was broken down)

By substituting these values into the equation, we have

15 = 0 x t + 1/2 x 4.27 x t^2

15 = 0 + 2.135t^2

15 = 2.135t^2

Dividing both sides of the equation by 2.135, we have

15/2.135 = 2.135t^2

t^2 = 7.026

t = square root of 7.026

t = 2.65

The time required is 2.65 s

The first human-made satellite, Sputnik I, had a mass of 83.4 kg and a momentum with a magnitude of 660,730 kg·m/s. What was the satellite’s speed? Round your answer to the nearest whole number.

Answers

The satellite’s speed is 7922.4 m / s if the Sputnik I, had a mass of 83.4 kg and a momentum with a magnitude of 660,730 kg·m/s.

p = m v

p = Momentum

m = Mass

v = Velocity

m = 83.4 kg

p = 660730 kg m / s

v = p / m

v = 660730 / 83.4

v = 7922.4 m / s

Momentum can be described as a mass in motion. It is the product of the object's mass and its velocity. It can also be described as the power held by a moving body that it can exert on another body.

Therefore, the satellite’s speed is 7922.4 m / s

When you drop a 0.37 kg apple, Earth exerts
a force on it that accelerates it at 9.8 m/s² to-
ward the earth's surface. According to New-
ton's third law, the apple must exert an equal
but opposite force on Earth.
If the mass of the earth 5.98 x 10²4 kg, what
is the magnitude of the earth's acceleration
toward the apple?
Answer in units of m/s².

Answers

The earth is accelerating toward the apple at a rate of 6.2 × 1025 m/s2.

How is this acceleration determined?

The apple weighs m = 0.37 kg.

The apple's speed when it approaches the earth's surface is 9.8 meters per second.

Earth's mass, M, is 5.98 × 1024 kg.

Using Newton's Second Law of Motion, we may now:

The strength of the force exerted by Earth on the apple is,

F = ma

⇒ F = 0.37 × 9.8

⇒ F = 3.626 N

We are informed that the apple must exert an equal but opposite force on Earth in accordance with Newton's third law of motion.

Therefore, the force exerted by the apple on Earth will be of the following magnitude:

F = 3.626 N

Let "A" be the acceleration of the earth relative to the apple in m/s2.

Thus,

The following will be used to determine how quickly the earth is moving toward the apple:

F = MA

⇒ 3.626 = [5.98 × 10²⁴] × A

⇒ A = 3.626 / [5.98 × 10²⁴]

⇒ A = 0.606 × 10⁻²⁴

A = 6.06 × 10⁻²⁵ m/s²
