A 5.80 x 103 kg delivery truck moving with a velocity of 20 m/shits a 1.50 x103 kg parked car. As a result of the impact, the carwas set in motion at 31.8 m/s. (Assume the car –truck to be anisolated system) (a) Sketch the situation. (b) Find the velocity ofthe truck immediately after the collision; (c) Find the kineticenergy of the car-truck system before and after the collision. (d)Is the car-truck collision elastic or inelastic? Explain (e) Whatis the change in momentum of the car? Assuming the collision timeto be 2 seconds, how much average impact force did the carexperience? (f)What is the change in the momentum of the truck?Solve for the impact force experienced by the truck.
