The mass of the airplane is m = 9010 kg. The plane travels at a constant speed around a circular path of radius R = 8.67 miles and makes one revolution every T = 0.115 hours. What is the magnitude of the lift force acting on the plane?
Suppose the second distance d were traveled in the opposite direction; you forgot something and had to return home at the same constant speed as found in part (a). What is the average velocity for this trip.
