Two disks of masses m(1) and m(2) are connected by a spring of force constant k. The lower disk of mass m(2)lies on a table and the upper disk is vertically above it. What vertical force F should be applied to the upper disk so that when the force is withdraw, the lower disk is lifted off the table?

A smooth semicircular wire-track of radius R is fixed in a vertical plane. One end of a massless spring of natural length 3R/4 is attached to the lowest point O of the wire-track. A small ring of mass m, which can slide on the track, is attached to the other end of the spring. The ring is held staionary at point P such that the spring makes an angle of 60 with the vertical. The spring constant K=mg/R. Consider the instant when the ring is released, and (i) draw the free body diagram of the ring, (ii) determine the tangential acceleration of the ring and the normal reaction.
