Chapter 4, Problem 55P

A 22(M)-kg airplane pulls two gliders, the first of mass 310 kg and the second of mass 260 kg, down the runway with acceleration 1.9 m/s² (Fig. 4.23). Neglecting the mass of the two ropes and any frictional forces, determine the magnitudes of (a) the horizontal thrust of the plane’s propeller; (b) the tension force in the first rope; (c) the tension force in the second rope; and (d) the net force on the first glider.
