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.

Correct Answer: 1 : 1

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.
