A block of mass m is connected to another block of mass M by a spring (massless) of spring constant k. The blocks are kept on a smooth horizontal plane. Initially, the blocks are at rest and the spring is unstretched. Then a constant force F starts acting on the block of mass M to pull it. Find the force on the block of mass m.

A block at rest slides down a smooth inclined plane which makes and angle 60 degree with the vertical and it reaches the ground in t1 seconds. Another block is dropped vertically from the same point and reaches the ground in t2 seconds. What is the ratio of t1 : t2 ?
