Question

question 4 (1 point) will a thrown ball or a dropped ball hit the ground first when dropped or thrown from the same height? a both the balls hit the ground at the same time. b the dropped ball will hit the ground first. c the less massive ball will hit the ground first. d the thrown ball will hit the ground first.

Explanation:

In the absence of air - resistance, the vertical motion of an object is determined by the acceleration due to gravity ($g$) and the initial vertical displacement. When dropped or thrown from the same height, if the initial vertical velocity component is the same (assuming the thrown ball is not thrown upwards or downwards vertically but horizontally for a fair comparison), both balls are in free - fall with the same acceleration $g$ and the same initial vertical position. So they will hit the ground at the same time.

Answer:

A. Both the balls hit the ground at the same time.
