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 dont 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
