A 1 kg ball and a 10 kg ball are dropped from a height of 10 m at the same time. In the absence of air resistance,

O the 10 kg ball will take 10 times the amount of time to reach the ground.
O the two balls will hit the ground at the same time. 0 there is not enough information to determine which ball will hit the ground first.
O the 10 kg ball will hit the ground first.
O the 1 kg ball will hit the ground first.

the two balls will hit the ground at the same time.

Explanation:

The time of dropping, in the following equation, is related to both the distance travel s and the gravitational acceleration g, which are the same for both ball (if we neglect air resistance), no matter what their mass are.

So the time it takes to drop 2 balls are the same. They will hit the ground at the same time.
