Question

A body is projected horizontally from the top of a building of height h, velocity of projection is u. Find:
1. The time of will take to reach the ground.
2. Velocity with which the body reaches the ground.

Answer 1

1.time taken=u/g+√2g(h+u×u/2g)
2.the velocity with which the body reaches the ground is √2g(h+u×u/2g)
