Question

Two bullets are fired with horizontally velocities of 50m/s and 100m/s from two guns at an height of 19.6m. which bullet will strike first

Answer 1

Both the bullets will strike the ground at the same time.
Initial vertical velocty is zero for both the bullets.

Hence time taken by both the bullets is sqrt(2H/g)
Where H is 19.6m and g is 9.8m/s^2
