Let the angle be cX=(ucosc)t =20×0.5×0.5 =5mY=(usinc)t-1/2gt^2 =20×root3/2 ×0.5 - 1/2 ×10×0.25 =7.4mResultant of x and y will be root of x^2+y^2= Root of 70.76 =8.94m

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.
