Physics Motion in a Straight Line JEE Main 2002

From a building two balls A and B are thrown such that A is thrown upwards and B downwards (both vertically). If and are their respective velocities on reaching the ground, then

(1)
(2)Correct
(3)
(4)their velocities depend on their masses

Answer: (2)

Solution

Both balls are thrown from the same height with the same speed (one up, one down). Ball A, thrown up, rises, stops and comes back to the point of projection with speed directed downward; from there its motion is identical to that of B. Equivalently, by
