A 100 g steel ball falls from a height of 1.8 m on to a metal plate and rebounds to a height of 1.25 m. Finda the p. e. of the ball before the fall (g = 10 m/s2),b its k. e. as it hits the plate, c its velocity on hitting the plate, d its k. e. as it leaves the plate on the rebound, e its velocity of rebound.
