A stunt pilot in an air show performs a loop-the-loop in a vertical circle of radius 3.70 103 m. During this performance the pilot whose weight is 740 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.

N

(b) At what speed will the pilot experience weightlessness?

m/s

(c) When the pilot is at the lowest point of the loop determine his apparent weight.

N
