I need help with this question *15 GO Figure 7-28 shows threeforces applied to a trunk that movesleftward by 3.00 m over a friction-less floor. The force magnitudes areF = 5.00 N, F2 = 9.00 N, and F, =3.00 N, and the indicated angle is 0=60.0°. During the displacement,(a) what is the net work done on thetrunk by the three forces and (b)does the kinetic energy of the trunkincrease or decrease?F2F%3DF3Figure 7-28 Problem 15.

The surface of the preceding problem is modified so that the coefficient of kinetic friction is decreased. The same horizontal force is applied to the crate, and after being pushed 8.0 m, its speed is 5.0 m/s. How much work is now done by the force of friction? Assume that the crate starts at rest.
Repeat the preceding problem, but this time, suppose that the work done by air resistance cannot be ignored. Let the work done by the air resistance when the skier goes from A to B along the given hilly path be —2000 J. The work done by air resistance is negative since the air resistance acts in the opposite direction to the displacement. Supposing the mass of the skier is 50 kg, what is the speed of the skier at point B ?
