Problem
A truck of mass 1000 kg is moving at 5.0 m/s on a level road when it collides elastically with a stationary rubber ball of mass 5.0 kg that is lying in its path. Treat the collision as perfectly elastic and one-dimensional.
(i) Calculate the speed and direction of the truck and of the ball immediately after the collision.
(ii) By comparing the truck’s speeds before and after the collision, comment on whether the collision produces any noticeable change in the truck’s motion.
(iii) Find the fraction of the truck’s initial kinetic energy that is carried away by the ball after the collision.
