Question

At the instant that a tennis ball is launched horizontally from a tennis ball launcher with a large force, an identical ball is dropped from the same height. Assuming air resistance does not affect them, which ball will hit the ground first?

A) neither, they would hit at the same time
B) the ball that was launched horizontally
C) the ball that was launched horizontally
D) None of the above

Answer 1

The tennis ball launched horizontally and the ball dropped from the same height will hit the ground at the same time.

Step-by-step explanation:

The answer to the question is A) neither, they would hit at the same time. When a tennis ball is launched horizontally from a tennis ball launcher with a large force and an identical ball is dropped from the same height, both balls will hit the ground at the same time as long as air resistance is ignored. This is because the vertical motion of a falling object is influenced only by gravity, and not by any horizontal forces. The horizontal velocity of the ball launched horizontally is constant and unaffected by its vertical motion or gravity.
