Solution

## The correct option is C Both will reach simultaneouslySince both the bullets are fired horizontally, vertical component of velocity for both the bullets will be zero. Also both are fired from the same height. From 2nd equation of motion for vertical displacement(−h), S=Vyt+12gt2 −h=0−12gt2 t=√2gh Also both bullets experience gravitational acceleration (−g) in downward direction. Hence both will take equal time to reach the ground
