If we drop a steel sphere and a ping pong ball from a height of 12 m, the steel sphere will ____
|
|
hit the ground first because it has more mass and encounters less friction
|
|
|
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: -The ping pong ball weight is much lower than the golf ball weight so will be balanced at a much lower speed. Weight does affect when an object reaches terminal velocity… so does it’s shape. In this case, the balls are about the same size, but the golf-ball is slightly more streamlined and more inclined to spin.
Detailed explanation-2: -Normally, when a ping pong ball is dropped, it will fall to the ground. This is due to gravity. Gravity is a force that pulls objects toward each other.
