Question

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

Answer 1

Answer: (C)

Both A & B strike the ground with same velocity

Answer 2

$v^{2} = u^{2} + 2gh \Rightarrow v = \sqrt{u^{2} + 2gh}$

so for both the cases velocity will be equal.
