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 83.9-kg water-skier has an initial speed of 6.3 m/s. Later, the speed increases to 10.1 m/s. Determine the work done by the net external force acting on the skier.
Would I use the equation
KEf-KE0 = 1/2mvf^2 - 1/2mv0^2 ?
