Solve the all parts of given problem:
Problem: A 720-kg car stopped at an intersection is rear-ended by a 1730-kg truck moving with a speed of 16.0m/s.
Part I: If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find the final speed of the truck?
Part II: Find the final speed of the car?
I need help to find the final speed of the truck.
