Problem-

The water skier in Figure 7-14 is at an angle of 35 with respect to the center line of the boat, and is being pulled at a constant speed of 14m/s. If the tension in the ton rope is 90N, (a) how much work does the rope do on the skier in 10secs? (b) How much work does the resistive force of water do on the skier in the same time?

answer-

(a) W= (90N cos35) (14m/s)(10secs)

= 10321.3J

(b)
