A plank of mass M and length L is placed at rest on a smooth horizontal surface. A small block of mass m is projected with a velocity v0 from the left end of it as shown in figure. The coefficient of friction between the block

as shown in figure. They are released from rest. Show that after they have moved a distance L their common speed is given by Two blocks are connected by a string
