Problem 28PE

Commercial airplanes are sometimes pushed out of the passenger loading area by a tractor. (a) An 1800-kg tractor exerts a force of 1.75×104 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.

Step-by-Step Solution:

Solution to 28PE

Step 1 of 4</p>

We need to calculate the mass of the aircraft which is pulled by a tractor of mass 1800 kg by exerting a force of on the backward direction. The total resisting force is given as 2400N. The acceleration of the system is .

We have to calculate the force exerted by the tractor if the frictional force on the aircraft is 2200N. We have to draw the free body diagram to illustrate the system of forces.
