Question

A body is projected horizontally with a velocity 29 m/s from a height 10 m, the
velocity on reaching the ground_______
m/s.
​

Answer 1

Answer:

When body reach at h=10 cm then the potential energy of body = mgh

When body is a about to reach the ground, Let it's velocity is V

Then according to conservation of energy

mgh=(mV*square) /2

Putting value we get V= 10 under root 2 m/s
