The most likely time for the instantaneous acceleration to be zero is t = 2.7 sec
What is instantaneous acceleration ?Instantaneous acceleration : The acceleration at any given point in the motion is provided by the continuous time function a(t), which is written as a function of time. The derivative of the velocity function is used to calculate it. The graph of velocity versus time's slope, or instantaneous acceleration, is a measure of motion.
The slope of the tangent line to the graph at any given point on the graph corresponds to the instantaneous acceleration there. The instantaneous acceleration of the particle is equal to 0 when this line is horizontal and has a slope of 0.
According to the plot, these times correspond to the velocity function's extrema, which can be found at t = 1.75, 2.75, 3.25, and for all t = 4.
Thus the most likely time is t = 2.7

We can see that the change in momentum from both cars is equal but has the opposite sign since I utilized the values of final velocities without rounding. The change in momentum of car B is 314 kg m/s.
What does total momentum mean in plain English?The rate of a substance's change in momentum is inversely proportional to the resultant force that was applied, and it moves in the same direction. We can then conclude that the force exerted equals the growth rate of momentum. Momentum is well-known to be equal to mass times velocity.
What changes the momentum?When a force that is out of balance results in a CHANGE IN ACCELERATION, momentum changes. To put it another way, a change in momentum always coincides with a momentum shift. You're right to associate time with time when you hear the word "impulse." The concept of impulse is the change in momentum caused by a force over a specific period of time.

When the distance between the two bodies of same mass is halved the mutual force of attraction between them becomes?.
When the distance between the two bodies is halved the gravitational force of attraction between them becomes one-fourth.
As indicated by Newton's law of attraction each article or body in the universe draws in every single item towards one another and that power of fascination is straight forwardly relative to the result of their masses and contrarily corresponding to the square of the distance between them.
The power of gravity between two articles will diminish as the distance between them increments. The two most significant elements influencing the gravitational power between two items are their mass and the distance between their focuses. As mass increments, so does the power of gravity, however an increment in distance mirrors a reverse proportionality, which makes that power decline dramatically.
At that point by Newton's All inclusive Law of Attractive energy;
F=GMm/R²
Where R is the distance between the bodies .
So , if R′ = 1/2R
Then, gravitational force,
F = G(Mm/R²)
After doubling the distance,
F′ = G{Mm/(1/2R)²} = G{Mm/(1/4)R²}
F = 1/4F′
Therefore, when the distance between the two bodies of same mass is halved the gravitational force between them becomes one-fourth.

An inflated balloon released from rest moves horizontally. The law that best explains this event is.
The law that is responsible for the fact that the inflated balloon released from rest moves horizontally is the law of action and reaction.
What is the force that is responsible?Let us note that according to the Newton's third law, action and reaction are equal and opposite. In this case, we are told that an inflated balloon released from rest moves horizontally. We know that the direction that the object moves must be in that of the applied force.
In this case, there is a horizontal force that is applied on the balloon and the effect of this force is that the balloon would have to move in the horizontal direction and this is in reaction to the horizontal force that has been applied.
This is therefore in line with the Newton third law that states that action and reaction are equal and opposite.

Explain the term Magnetic field region?The region of space close to an electric current, magnetism, or a moving charged object is called the magnetic field. Since it describes the direction and magnitude at each point, it is a vector field. At an intense magnetic field location, the magnetic field lines congregate there.According to Ampere's law, the magnetic field's dot product times a closed path equals proportional to the current that flows through the path.

How is the weight calculated?Given ,
density (d) = 7800 kg/m³
D = 2.05 cm = 0.0205 m
r = D/2 = 0.0205 / 2 =0.01025 m
h = 92.8 cm = 0.928 m
The weight is calculated by ,
W = m × g
But, to find mass (m)
m = d × V
The volume of the rod, because is cylindrical, is,
V = π × r² × h
∴ V = 3.14 × (0.01025)² × 0.928
∴ V = 3.14 × 1.051 × 10⁻⁴ × 0.928
∴ V = 3.0625 × 10⁻⁴
Now to calculate mass,
m = d × V
∴ m = 7800 × 3.0625 × 10⁻⁴
∴ m = 2.3887 Kg
Now, for calculating weight
W = m × g

A car tire has a radius of 15 inches. The rate of spin approximately in revolutions per minute is 672 revolutions per minute.
Given that, radius = 15 inches
Speed of the car = 60 miles per hour = 60*5280 = 316800 feet per hour = 31680*12 inches per hour = 3801600/60 inches per minute = 63360 inches per minute.
Angular velocity ω = ?
We know that, v = r ω
where, v is linear velocity
r is radius
Making ω as subject,
ω = v/r = 63360/15 = 4224 radians per minute
= 4224/ 2π revolutions per minute = 672 revolutions per minute
Thus, the rate of spin is approximately 672 revolutions per minute.

As a warm moist air mass moving northward collides with a strong cold air mass moving southward, what observations will most likely be made?.
What will most likely be observed as a strong cold air mass going southward collides with a warm moist air mass moving northward? Clouds will probably start to form.
Which is mass?As a measure of inertia, which is a fundamental characteristic of all matter, mass is used in physics. Effectively, it is the resistance a body of matter offers to a change in its speed or position as a result of the application of a force. The change caused by a force applied is proportional to the mass of the body.
What do mass and weight mean?How much matter an object contains is determined by its mass. Weight is a unit of measurement that represents the force of gravity acting on an object. Whereas weight is location-dependent, mass is not.

A boat moves through the water with two forces acting on it. One is a 1,725-N forward push by the water on the propeller, and the other is a 1,000-N resistive force due to the water around the bow. (a) What is the acceleration of the 1,100-kg boat? m/s 2(b) If it starts from rest, how far will the boat move in 17.5 s? m(c) What will its velocity be at the end of that time? m/s
A boat travelling through the sea while being affected by two forces resulted in the following calculations: acceleration = 0.2, distance = 10 meters, and final velocity = 2 m/s.
Newton's Second Law of Motion is given by this formula;
acceleration=[tex]\frac{Netforce}{mass}[/tex]
Explain what an acceleration is.Acceleration is the rate of change in both the direction and speed of velocity over time. So when something moves faster or more slowly in a straight line, it is referred to as pushed.
What does "acceleration unit" mean?A metre per secondly per second (m/s2) is used to measure acceleration. Definition. The snewton is the unit of force responsible for producing an accelerating of one m / s2 per second when applied to a mass about one kilogram.
