Chapter 7, Problem 26CQ
Suppose that on a perfectly still day, a sailboat enthusiast decides to bring along a powerful battery-operated fan in order to provide an air current for his sail, as shown in the diagram.
- a. What are the directions of the change in momentum of the air at the fan and at the sail?
- b. What are the directions of the forces acting on the fan and on the sail due to these changes in momentum?
- c. Would the sailor be better off with the sail furled (down) or unfurled (up)? Explain.

If the answer is 2.8, -2.8 or -8.4, it is not CORRECT
Three blocks, light connecting ropes, and a light frictionless pulley comprise a system,
as shown in the figure. An external force of magnitude P is applied downward on block A,
causing block A to accelerate downward at a constant 2.5 m/s2. The tension in the rope
connecting block B and block C is equal to 60 N.
(a) What is the magnitude of the force P?
(b) What is the mass of block C?
