A hang glider and its pilot have a total mass equal to 113 kg. While executing a 360° turn, the glider moves in a circle with a 9 m radius. The glider's speed is 11 m/s. (Assume the glider turns along the horizontal plane.)
(a) What is the net force on the hang glider?
(b) What is the acceleration?
