Physics Motion in a Straight Line JEE Main

From the top of a tower, two stones whose masses are in the ratio are thrown — one straight up with an initial speed and the second straight down with the same speed . Neglecting air resistance,

(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 does not enter the kinematics of free fall. The stone thrown upward with speed returns to the point of projection with speed directed downward — identical to the
