Question

A power boat pulls a water skier 2.6 km maintaining a

tension of 250 N in the rope to the skier. How much work is
done on the water skier by the rope?

Answer 1

W = 650 [kJ]

Step-by-step explanation:

The definition of work is denoted by the product of force by the distance traveled by the body, this distance traveled corresponds to the direction of the force.

In this case we have:

d = distance = 2.6[km] = 2600 [m]

F = force = 250 [N]

W = F*d = 250 * 2600 = 650000 [J] or 650 [kJ]
