Big commercial airplanes are sometimes pushed to an area by a tractor. A 1800-kg tractor exerts a force of 1.75x 104 N backward on the pavement, and the system experiences forces resisting motion that total 2400 N. Calculate the force exerted by the tractor on the airplane, assuming 2200 N of the friction is experienced by the airplane and the acceleration is 0.15 m/s2.
