Both will reach the ground simultaneously.

Vedclass · Answer

(C) When ball-$1$ is projected horizontally from the top of a tower and ball-$2$ is dropped vertically at the same instant,both balls experience the same vertical acceleration due to gravity,$g$.Since the initial vertical velocity for both balls is $u_y = 0$ and they fall through the same vertical height $h$,the time taken to reach the ground is given by the kinematic equation $h = \frac{1}{2}gt^2$.Solving for time,we get $t = \sqrt{\frac{2h}{g}}$.Since $h$ and $g$ are the same for both,the time $t$ is identical for both balls.Therefore,both balls will reach the ground simultaneously.

Simultaneously,from the top of a tower,when ball-$1$ is thrown horizontally and ball-$2$ is just dropped,in the absence of air resistance,which among the following options is correct?
