Question

show that the time required for a ball to go up and come down is equal

Answer 1

Hey Mate! Here's ur answer.
When we throw a ball vertically up the initial velocity (u) = x & the final velocity (v)= y vise versa when the ball comes down vertically the initial velocity(u) = x and the final velocity(v) = y. So the time required for the object to go up and come down is equal. Hence Proved.
