Use the values from PRACTICE IT to help you work this exercise. Suppose the same two vehicles are both traveling eastward, the compact car leading the pickup truck. The driver of the compact car slams on the brakes suddenly, slowing the vehicle to 5.77 m/s. If the pickup truck traveling at 17.5 m/s crashes into the compact car, find the following. (a) the speed of the system right after the collision, assuming the two vehicles become entangled 13.71 ✔ m/s (b) the change in velocity for both vehicles Avtruck <-38 m/s Av car <-8 ✔ m/s (c) the change in kinetic energy of the system, from the instant before impact (when the compact car is traveling at 5.77 m/s) to the instant right after the collision
