28. Commercial airplanes are sometimes pushed out of the
passenger loading area by a tractor. (a) An 1800-kg tractor
exerts a force of 1.75x10* 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.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
