64. A man standing on a edge of a cliff throws a stone vertically upwards with a certain speed. He then throws another stone downwards with the same speed. Find the ratio of the speeds of the two stones when they hit the ground. A.1 : 1 B.1 : 2 C.1 : 4 D.Cannot be found from the given information.
Option A Solution: When man throws the stone upward with speed u and downward with speed u, the initial velocity (from the cliff) will be the same. Hence, this will result in equal final velocity. Hence the ratio is 1:1.
