Question

On the earth, a stone is thrown from a height in a direction parallel to the earth’s surface while another stone is simultaneously dropped from the same height. Which stone would reach the ground first and why?

Philoid · Accepted Answer

Both the stones will reach the ground simultaneously. The acceleration due to gravity acts on both, irrespective of their horizontal or vertical path.

For stone 1,

U = 0

A =g

Distance, s = h

For stone 2

A=g s = h

Initial velocity in vertical direction is zero

Thus, here also
