A resistance to change in motion describes inertia.

Inertia<span> is the resistance of any physical object to any change in its state of motion (this includes changes to its speed, direction or state of rest). It is the tendency of objects to keep moving in a straight line at constant velocity.</span>

The correct answer between all the choices given is the last choice. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Answer:

average value of the resulting force

Explanation:

The average module value of this resulting force is equivalent to 2.0. 10⁵ N.

The impulse of a force can be calculated by the product of the intensity of the force applied by the time interval in which it is applied -

I = F.Δt

Where,

F = Strength in Newtons

Δt = time interval in seconds

I = Impulse in N.s

The impulse of a force is equivalent to the variation of the amount of movement it causes in the body.

I = ΔQ

The amount of movement is a vector quantity that results from the multiplication of the mass of a body by its speed. Its direction and direction are the same as the velocity vector of the body.

Q = m-V

As the car goes to rest after the application of force, the amount of final movement of the car is equivalent to zero.

I = 0 - mV

F. Δt = - mV

F. 0,1 = - 1000. 20

F = - 20000/0,1

F = 200,000 N

F = 2,0. 10⁵ N
