|
|
hit the ground first because it has more mass
|
|
|
hit the ground second because it takes longer to accelerate
|
|
|
hit the ground at the same time as the ping pong ball

None of the above

Explanation:
Detailed explanation-1: -Answer. When we drop a ping pong ball and a bowling ball at the same time, the bowling ball lands on earth the first. It is due to air resistance.
Detailed explanation-2: -The bowling ball has a greater mass, so there’s more stuff for gravity to act on. In that sense, gravity is pulling on it more. But it still doesn’t fall any faster.
Detailed explanation-3: -If you were to drop a ping pong ball, and a golf ball at the same time, from the same height, with normal air pressure, the golf ball would hit the ground first. Since the ping pong ball is lighter, it will lose more energy from the air resistance, than the golf ball.
