ANSWER:

Step 1 of 3

(a) In the given case, we need to calculate the work done by the rope on the skier in time .

As shown in the given figure, the skier is at an angle  relative to the centerline of the boat and the boat is moving with a constant speed of . The tension in the rope is given to be .

The work done by the rope on the skier is given by,

                                        

Using fundamental equation of speed, we have displacement as
