    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 and B strike the ground with same velocity

    D)  None of these

    Correct Answer: C

    Solution :

    [c] \[{{v}^{2}}={{u}^{2}}+2gh\Rightarrow v=\sqrt{{{u}^{2}}+2gh}\] So, for both the cases velocity will be equal.
