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.
Answer: Option A
Solution (By Examveda Team)
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.

what about the gravitational force acting when the stone which is in upward direction.. it will increase the gravitational force right
