Two cars of identical mass and velocity are driving down the road. car a stops by slamming on the brakes. car b gently rolls to a stop. which car experienced the greater impulse?

Car A experienced a greater impulse, because it stopped in a shorter amount of time.

Impulse is defined as the change in force over time. Since both cars have the same mass, as well as the same initial and final velocities, the only factor that makes a difference is the time taken to achieve the stop.

Car A experienced a larger impulse, as a result of it stopped during a shorter quantity of your time.

Impulse is outlined as the modification in force over time. Since each car have a similar mass, moreover because the same initial and final velocities, the sole issue that creates a distinction is that the time is taken to achieve the stop.

Explanation:

Impulse (physics), in mechanics, one thing that changes the momentum of AN object; the integral of a force with relevancy time. Specific impulse, the modification in momentum per unit mass of propellant of a system.
The difference is in the time taken to stop the car.
