JEE Main Physics question

Physics Motion in a Straight Line JEE Main

From the top of a tower two stones, whose masses are in the ratio 1:2, are thrown one straight up with an initial speed and the second straight down with the same speed . Then, neglecting air resistance [K CET 2005]

(A)The heavier stone hits the ground with a higher speed
(B)The lighter stone hits the ground with a higher speed
(C)Both the stones will have the same speed when they hit the groundCorrect
(D)The speed can't be determined with the given data

Answer: (C)

Solution

Mass doesn't affect free-fall kinematics; by symmetry, the stone thrown up returns to the tower-top level
