Question

A ball is dropped downward from the roof of a building and simultaneously another ball is thrown in a horizontal direction from the same roof, when and where will the balls reach the ground?

• A. Both will reach at same time and same place.
• B. The first ball will reach later than the second ball at same place.
• C. The second ball will reach later than the first ball at different place.
• D. Same time but different places.

Answer 1

The correct option is D Same time but different places.

Since the second ball has horizontal velocity so, it will fall at different place from the first ball. But since the vertical velocity is same for the both balls, hence they will fall at the same time.
