___ N

(b) At what speed will the pilot experience weightlessness?
193.2

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

____ N

A stunt pilot in an air show performs a loop-the-loop in a vertical circle of radius 3.81 (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? 193.2 (c) When the pilot is at the lowest point of the loop determine his apparent weight. ____ N During this performance the pilot whose weight is 693 N, maintains a constant speed of 2.15

Explanation / Answer

a) Wapp = mg - mv^2/R = mg (1- v^2/gR) = 693*(1-((2.15102^2)/(9.81*3.70103))) = 604.68 N

b) Wapp = 0

mg = mV^2/R

V = sqrt(gR) = sqrt(9.81*3.70103) = 6.0255 m/s

c) Wapp = mg -+mv^2/R = mg (1+ v^2/gR) = 693*(1+((2.15102^2)/(9.81*3.70103))) =781.31 N
