M = 1kg, Force = FTherefore, W= F*x = F(2-0) = 2FF = dp/dt = d(mv)/dt = m*dv/dt = d(2√x)/dt = 2*d(√x)/dt =2*1/2*1/(√x) = 1/(√x) = 1/√2Therefore, W = 2*1/√2 = √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.
