Physics

The situation that demonstrates impulse being applied is a car hitting a wall and stopping.

When the car hits the wall, a large force acts on the car over a short period of time. The car's momentum changes from a non - zero value (while it was moving) to zero (when it stops).

There is a change in momentum, so an impulse is applied. The force exerted by the wall on the car causes this change in momentum.

Option B

A car traveling at constant speed

The momentum of the car remains constant because its velocity is constant. There is no change in momentum (Δp = 0), so no impulse is being applied. The net force acting on the car is zero (assuming no external...
