Consider the system shown, with m1 = 2.0 kg, m2 = 3.0 kg, and α = 30o. The force F acts horizontally to the left and the kinetic coefficient of friction between m1 and the incline is μk = 0.40. The mass m2 is moving up at a constant speed.

(a) What is the magnitude of F?

(b) If the mass m2 moves up a distance of 2.0 m,

what is the work done by the following forces

acting on m1: (i) the force F, (ii) the normal force

due to the incline, (iii) the tension, (iv) friction, and

(v) gravity? What is the net work done on m1 by all the forces?
