Question

From a high tower one ball is dropped from rest and the second ball is simultaneously projected horizontally. Neglecting air resistance which ball will reach the ground earlier? ​

Answer 1

They will reach the ground at the same time.

Because where h is the height of the tower and g is acceleration due to gravity. Since for both the balls h and g are the same, the time must be the same hence both the balls will reach the ground at the same time.
