Question

1)A jet airplane is in level flight. The mass of the airplane is m = 9010 kg. The plane travels at a constant speed around a circular path of radius R = 9.77 miles and makes one revolution every T = 0.129 hours. What is the magnitude of the lift force acting on the plane? At what angle is the airplane banked?
