Dear Student

Let H be the height of tower

V² = u² + 2*a *S

(-3u)² = u² + 2* (-g) (-H)

H = 8u²/2 g

= 4u²/g

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.
