PRACTICE IT Use the worked example above to help you solve this problem. An pickup truck with mass 1.88 x 10° kg is traveling eastbound at +14.1 m/s, while a compact car with mass 9.48 x 102 kg is traveling westbound at -14.1 m/s. (See figure.) The vehicles collide head-on, becoming entangled. (a) Find the speed of the entangled vehicles after the collision. 4.7 m/s (b) Find the change in the velocity of each vehicle. Δν. truck = -9.4 m/s Δν car = 18.8 m/s (c) Find the change in the kinetic energy of the system consisting of both vehicles. -250633 EXERCISE HINTS: GETTING STARTED I I'M STUCK! 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 5.44 m/s. If the pickup truck traveling at 17.0 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 m/s (b) the change in velocity for both vehicles Δν, truck m/s Av car m/s
