Question

IP A tow rope, parallel to the water, pulls a water skier directly behind the boat with constant velocity for a distance of 75 m before the skier falls. The tension in the rope is 100 N.
Is the work done on the skier by the rope positive, negative, or zero?
Explain.
Calculate the work done by the rope on the skier.

Answer 1

The work is done against the skier, we call it negative work, and the magnitude of the work done on the skier by the rope is 7500 J.

Work done on the skier

The work done on the skier by the rope is in opposte direction of the water skier which caused the water skier to fall after some given period of time. Since the work is done against the skier, we call it negative work.

The magnitude of the work done on the skier by the rope is calculated as follows;

W = Fd

where;

F is the applied force on the rope

d is the distance moved by the skier

W = 100 x 75

W = 7500 J

Thus, the magnitude of the work done on the skier by the rope is 7500 J.
