An airplane is doing a vertical loop in the air. The airplane goes at a velocity of 320 and at the top of the loop, n=500N. The pilot weighs 62kg.
calc the radius of the loop
vertical loop, given: v=320, n at the top=510N, m=62kg
i don't know what eqn i use to find the radius of the loop..
What is n?
You will be using centripetal force=weight of plane and pilot
Normally, if at the top centforce exactly equals weight.
but I don't know what you mean by n.
