Calculating Work from Speed Change: Water-Skiing Physics Explained!
Chapter 6, Problem 6.86(choose chapter or problem)
A water-skier is being pulled by a tow rope attached to a boat. As the driver pushes the throttle forward, the skier accelerates. A 70.3 kg water-skier has an initial speed of 6.10 m/s. Later, the speed increases to 11.3 m/s. Determine the work done by the net external force acting on the skier.

QUESTION:
A water-skier is being pulled by a tow rope attached to a boat. As the driver pushes the throttle forward, the skier accelerates. A 70.3 kg water-skier has an initial speed of 6.10 m/s. Later, the speed increases to 11.3 m/s. Determine the work done by the net external force acting on the skier.
ANSWER:Step 1 of 3
Consider the given data as follows.
The mass of the water-skier m = 70.3 kg.
The initial speed of the skier \({{v}_{i}}=6.10\text{ m/s}\).
The final speed of the skier \({{\text{v}}_{f}}=11.3\text{ m/s}\).
Using this information, we can calculate the work done by the net external force acting on the skier.
