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..
again, what is n? n is not a commonly known symbol, at least here in Texas.
n is normal force
If n is the force of the seat pushing on the pilot at the top of the loop, then
n + mg = m V^2/R, the centripetal force
Solve for R. You need to state what your units of velocity are. They should be in m/s if you expect the formula to work with Newtons, kg and meters for the other terms
