A 2000 kg plane does a vertical loop with radius 600 m at a velocity of 120 m/s. At the very top of the loop, what is the force from the air required?

Plane's mass = 2000 kg

Radius = 600 m

Velocity = 120 m/s

2. Relevant equations

F = (mv^2)/R

Wt = mg

Net F-sub y = ma = 0

3. The attempt at a solution

-Wt -Fcentripetal + Fair = 0

-19600 N - 48000 N + Fair = 0

Fair = 67600 N
