resistive force equal to kv where k=1.6kgm1.The car is travelling at its maximum possible speed when it smashes into a brick wall, which brings it to an immediate halt. What magnitude of impulse does the wall exert on the car? A more realistic scenario would be the car rebounding. If the car rebounds with 10% of it's initial kinetic energy, and the impact lasts for 2 milliseconds, find the average force exerted by the wall on the car.
