Question
A 1500-Kg sports car traveling at the speed of 8.00 m/s collides into the rear end of a 2500-Kg
SUV stopped at a red light. After the collision, the two cars lock together and slide forward as one
object.
a) Compute the final velocity of the cars after the collision.
b) Compute the total kinetic energy before and after the collision.
c) How much energy was dissipated in the collision? What happens to it?
