In the figure, a small block of mass m = 0.031 kg can slide along the frictionless loop-the-loop, with loop radius R = 19 cm. The block is
released from rest at point P, at height h = 5R above the bottom of the loop. What are the magnitudes of (a) the horizontal component
and (b) the vertical component of the net force acting on the block at point Q? (c) At what height h should the block be released from
rest so that it is on the verge of losing contact with the track at the top of the loop? (On the verge of losing contact means that the norma
force on the block from the track has just then become zero).
