In the figure, a small block of mass m = 0.022 kg can
slide along the frictionless loop-the-loop, with loop radius
R = 15 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 normal force on the
block from the track has just then become zero).
