Question

(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.

A stunt pilot in an air show performs a loop-the-loop in a vertical circle of radius 181 A stunt pilot in an air show performs a loop-the-l 10^2 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 A stunt pilot in an air show performs a loop-the-l 10^3 m. During this performance the pilot whose weight is 693 N. maintains a constant speed of 215

Explanation / Answer

a) Apparent weight is the force the pilot applies to the seat which is currently above. The downward force is the pilot's weight 693 N, the upward force is mv^2/r = 857.94 N so the apparent weight is 857.94-693=164.94 N

b) v^2/r = g
v = 193.2 m/s

c) 693+857.93 = 1550.94N
