Question

From the top of a building a ball A is dropped while another ball B is thrown horizontally at the same time. Then,

• A. the ball A hits the ground first
• B. the ball B hits the ground first
• C. both A & B hit the ground at the same time
• D. any ball may hit the ground first

Time of flight is always dependent on height of fall for a freely falling body, which is the same for both the cases.

Hence, option C is correct.
