Two bullets are fired with horizontal velocities of 50m/s and 100m/s from two guns at a height of 19.6m . After how much time will the bullets strike the ground and which one will strike first?

Solution

Height of bullets from ground = 19.6m

H =(1/2)gt^2

t = squroot(2h/g)
t = squroot(2*19.6/9.8)
t = squroot(4)
t = 2 s
So both bullet will take 2 second to reach ground at same time.
