centripetal acceleration = v^2/R
Lift of wings = F
weight = m g = F cos 20
so F = m g/cos 20
centripetal force = F sin 20
= m g sin 20 / cos 20 = m g tan 20
centripetal force = m Ac = m v^2/R
so
m v^2/R = m g tan 20
so
R = v^2/(g tan 20)
An airplane is circling an airport by traveling a horizontal circular path at a speed of 400 km/h. The bank angle of the wings is 20 degrees. What is the radius of the circular path the plane is flying?
I honestly do not know where to start this. And it is an algebra-based Physics 1 AP class I'm taking.
