Commercial airplanes are sometimes pushed out of the passenger loading area by a tractor, and 1800 kg tractor exerts a force of 1.804 to the 4th N backwards on the pavement and the system experiences forcing resisting motion that total 2400 N if acceleration is 0.120 m/s squared what is the mass of the airplane in kilograms. Calculate the force in newtons exerted by the tractor on an airplane assuming 2250 N of friction is experienced by the airplane
