Answer:

[tex]\boxed {\boxed {\sf -6 \ m/s^2}}[/tex]

Explanation:

Acceleration is the change in velocity with respect to time. We are given the velocity and time, so we will use the following formula to find acceleration.

[tex]a= \frac {v_f-v_i}{t}[/tex]

The car slowed down, so the final velocity was 10 meters per second and the initial velocity was 40 meters per second. It slowed down in 5 seconds.

Substitute these values into the formula.

[tex]a= \frac{ 10 \ m/s - 40 \ m/s}{5 \ s}[/tex]

Solve the numerator and subtract.

[tex]a= \frac{ -30 \ m/s}{5 \ s}[/tex]

Divide.

[tex]a= -6 \ m/s/s[/tex]

[tex]a= -6 m/s^2[/tex]

The acceleration of the car is -6 m/s² or -6 meters per second squared. The acceleration is negative because the car slowed down.

The velocity of the horse is 0 m/s, so the correct option is C.

The velocity is a vector that is given by the rate of change of the displacement.

[tex] v = \frac{d}{t} [/tex]

Where:

d: is the displacement

t: is the time      

Since in the horse track the starting point and the finish line are at the same point, the velocity of the horse is zero because the velocity depends on the direction of the displacement, and here the displacement is zero (the horse returns to the starting point).  

Therefore, the correct option is C: 0 m/s.

The solar system is very large with the boundaries located around the Orth cloud 100,000 Astronomical Units away

The correct option for, the distance to the nearest star if the solar system were the size of a campus is the option;

About a mile away

The reason the above selection is correct is as follows:

The ratio of the area of the solar system to the area of a campus = (π × (10⁵ × 149.6 × 10⁶)²)/(109.2651) = 6.4347487 × 10²⁴

Therefore, the linear scale factor ≈ √(6.4347487 × 10²⁴) ≈ 2.5366807 × 10¹²

Therefore, the corresponding distance to the distance of the nearest star to the solar system, X is given as follows;

X = (40,208,000,000,000 km)/(2.5366807 × 10¹²) ≈ 15.85 km ≈ 9.85 miles

Given that compared with the largest campus the distance is at most approximately 9.85 mile, if the solar system is taken to be a much smaller campus, the distance of the closest star Proxima Centauri will be about a mile away

b.) (kg/s)(m/s) = force (N)

c.) (kg/s)(m/s) = force (N)

d.) (kg/s)(m/s) = force (N)

The units of the quantity described by each of the following

Force is defined as the product of mass and acceleration of the body. The unit of force is Newton or kgm/s². Mathematically,

Force = mass* acceleration

Unit of mass = kg

Unit of acceleration = m/s²

Unit of Force = kg * m/s²

Unit of force is therefore also expressed as kgm/s²

• This question comes from the study of electrostatics.

Materials that can be charged from the options are; plastic and glass.

• Now, among the 3 listed materials, plastic and glass are insulators whereas metal is a conductor because it can conduct electricity.

• With respect to insulators and conductors as regards charging by electrostatics, we can say that in conductors if you charge a portion of them, the charges inside will have the freedom of movement. However, inside of the material, If a charge is added in another portion of the conductor, the previously introduced charges will combine to neutralize this new charge.

• With respect to insulators, the charges that are put at the surface of the object will remain there because unlike conductors, these insulators do not allow for freedom of movement of charges inside the material that could neutralize.

• Thus, the materials that can be charged by rubbing are plastic and glass.

Total displacement of the car = (0+150) Km = 150 Km

Total time taken = 2 hours

Average velocity = 150/2 Km/h = 75 Km/h

A car travels 150 km in the north direction and it takes 2 hours to cover the distance then the velocity of the car will be 75 km/hr.

Velocity is the rate at which a moving object's direction changes as perceived from a certain vantage point and measured by a particular unit of time. Kinematics, the area of special relativity that investigates how bodies move, starts with the fundamental idea of speed.

In order to be explained, the scientific vector quantity known as velocity needs to have both a magnitude and a direction.

As per the provided information in the question,

The total displacement, D = 150 km north.

Total time is taken by the car, t = 2 hours.

Then, the velocity (v) of the car will be,

v = D/t

v = 150/2

v = 75 km/hr.

The acceleration-time graph is used to show the relationship between the acceleration of a body and time.

Let:

[tex]a \to[/tex] acceleration

[tex]t \to[/tex] time

From the question, we have the following parameters:

[tex](a_1,t_1) = (0,0)[/tex]

[tex](a_2,t_2) = (0.25,6.5)[/tex] ---- when the robot accelerates

[tex](a_3,t_3) = (0,57)[/tex] ----- when the robot travels without acceleration

[tex](a_4,t_4) = (-0.60,2.7)[/tex] ---- when the robot decelerates

To represent this on an acceleration time graph, we consider the following:

The total time (t) spent by the robot is 66.2 seconds

This is calculated as follows:

[tex]t = 6.5 + 57 + 2.7[/tex]

[tex]t = 66.2[/tex]

Answer:

you stop the ball or bring it to a different direction

Explanation:

i don't know if this helps. i didn't take physics yet. but i hope this helps.

If the force remains constant, then the decrease in the mass of the ball will increase the acceleration of the ball.

Force acting on a body can be defined as the changes in the state of the body of motion or rest. Force can change the speed and the direction of the moving body. The force acting on an object is related to factors which are mass and acceleration of the body.

The mathematical expression from the 2nd law of motion for force can be written as:

F = ma

We can express this equation as:

a ∝ 1/m

Therefore, the acceleration of a moving body is inversely proportional to the mass of that body.

Therefore, if we are applying the constant force on the ball, then this force can produce a greater change in the motion of the ball only if the mass of the ball will be less. Then the acceleration of the moving ball will increase.
