Question

find an
an expression for the initial velocity to be
imparted to a body so as to reach a height h​

Answer 1

Answer: Here is your answer

Explanation:

As it is  at maximum height it will have only potential energy no kinetic energy because of zero velocity. Hence P.E=mgh

But when it is on the ground it has no height from the ground hence P.E is zero where K.E has a value of mgh because energy is conserved at every point.

Hence, option D is the correct answer
