Question

(a) What is the pilot's apparent weight at the lowest point of the circle if his true weight is 821 N?
N

(b) What is his apparent weight at the highest point of the circle?
N

(c) Describe how the pilot could experience weightlessness if both the radius and the speed can be varied. Note: His apparent weight is equal to the magnitude of the force exerted by the seat on his body. Under what conditions does this occur?

This answer has not been graded yet.

(d) What speed would have resulted in the pilot experiencing weightlessness at the top of the loop?
m/s

Explanation / Answer

a. aparent weight =true weight +mv^2/r =821 +(821/9.8)*200^2/3570 =1759.66

b. aparent weight at highest point = true weight - mv^2/r =821 - (821/9.8)*200^2/357 = -117.66

c. weighlesnes will be there if aparent weight will be zero , hence if radius is decreased and velocity be increases . pilot will be feel weightless

d. for weighless

821 =(821/9.8)v^2/3750

v =191.7 m/s

any velocity greater than 191.7 will make pilot feel weightless
