Question

A ball P is dropped vertically and another ball Q is thrown horizontally with the same speed from the same height at the same time. If air resistance is neglected, then:

G1 Physics · Accepted Answer

Both balls have identical vertical initial velocity (zero) and identical vertical acceleration g. Horizontal velocity does not affect fall time, so both hit the ground together. Hence option C.
