Commercial airplanes are sometimes pushed out of the passenger loading area by a tractor.

(a) An 1800-kg tractor exerts a force of 1.75 x 10^4 N backward on the pavement, and the system experiences forces resisting motion that total 2400 N. If the acceleration is 0.150 m/s2, what is the mass of the airplane?

(b) Calculate the force exerted by the tractor on the airplane, assuming 2200 N of the friction is experienced by the airplane.

(c) Draw two sketches showing the systems of interest used to solve each part, including the free-body diagrams for each.
