Question

A stone through vertically upward with initial velocity you reach a height h before coming down shown that the time taken to go up is same as the time taken to come down

Answer 1

yes the time taken by stone to go upwards is same as time taken by it to come down
In physics it is called as that time of ascent is equal to the time of descent.
Also time of ascent and descent = initial velocity / acceleration due to gravity
and total time of flight is = 2* (initial velocity / acceleration due to gravity.)
