Let initial velocity is u and time of flight is T then

h = ut1 – ½g(t1)²

and

0 = u – g(T/2)

and for downward motion

h = ½g(t2 – T/2)²

From aboveequations

T = t1 + t2.

Hope it clears.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
