    A small block of mass 20 kg rests on a bigger block of mass 30 kg, which lies on a smooth horizontal plane. Initially the whole system is at rest. The coefficient of friction between the blocks is 0.5. The horizontal force, F = 50N, is applied on the lower block. The work done by frictional force on upper block in \[t=2s\] is \[n\times 10J\]. Find n.
