Q. Two balls $A$ and $B$ of same masses are thrown from the top of the building. $A$, thrown upward with velocity $V$ and $B$, thrown downward with velocity $V$, then
A) Velocity of $A$ is more than $B$ at the ground
B) Velocity of $B$ is more than $A$ at the ground
C) Both $A$ & $B$ strike the ground with same velocity
D) None of these
Explanation
(c) $v^{2} = u^{2} + 2gh \Rightarrow v = \sqrt{u^{2} + 2gh}$
So for both the cases velocity will be equal
