apply work energy theorem
kinetic energy = work done by friction + work done by spring
½*m*v2 = umg*x + ½*k*x2
½*2*42 = x*2*10*x + ½*10*x2
16 = 25*x2
so x = 4/5 m
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.
