A stunt pilot in an air show performs a loop-the-loop in a vertical circle of radius 2.97 103 m. During this performance the pilot whose weight is 835 N, maintains a constant speed of 2.25 102 m/s.
(a) When the pilot is at the highest point of the loop determine his apparent weight.
(b) At what speed will the pilot experience weightlessness?
(c) When the pilot is at the lowest point of the loop determine his apparent weight.
