A 1050-kg sports car is moving westbound a11S.0 m/s on a level road when it collides with a 632O-kg truck driving east on the same road at 10.0 m/s. The two vehicles remain locked together after 1he collision.
(a) What is the velocity (magnitude and direction) of 1he two vehicles just after 1he collision?
(b) At what speed should the truck have been moving so that it and car are both stopped in the collision?
(c) Find the change in kinetic energy of the system of two vehicles for the situations of part (a) and part (b). For which situation is the change in kinetic energy greater in magnitude?
