a=kxa=vdv/dxadx=vdvkxdx=vdvkx^2/2=v^2/2kx^2/2+C = v^2/2if x=0 , velocity = u C = u^2/2thus,v^2/2 = kx^2/2 + u^2/2 v^2 = u^2 + kx^2we have a = kxv^2 = u^2 + 2ax = u^2+ 2kx.xv^2 = u^2 + 2kx^2

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.
