A car of mass m is initially at rest on the boat of mass M tied to the wall of dock through a massless A strip of wood mass M and length l is placed on a smooth horizontal surface. An insect of mass m starts from rest at one end of the strip and walks to the other end in time t moving with a constant speed. The speed of the insect as seen from the ground is
