A block of mass m = 4.30 kg is released from rest from point circle a and slides on the frictionless track shown in the figure below. (Assume ha = 5.20 m.)
(a) Determine the block's speed at points circle b and circle c.
point circle b
point circle c
(b) Determine the net work done by the gravitational force on the block as it moves from point circle a to point circle c.
