A plane flying at 720 kilometres per hour loops the loop. What must the radius of the loop be so that the maximum force of the pilot on the seat is 5 times her weight?
Just wondering how if I am doing this correctly (:
r = ? v = 200m/s g = 9.8m/s^2 m = ?
So, at the top of the loop Reaction force = 0 therefore
R = 0, mv^2/r = mg
v = [tex]\sqrt{rg}[/tex], r = v^2/g
Therefore; Radius = 200^2/9.8 = 4.081km.
After finding this how would i find the force exerted on pilot?
Thanks.
