Question
Go 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 $6.10 \mathrm{m} / \mathrm{s}$. Later, the speed increases to $11.3 \mathrm{m} / \mathrm{s} .$ Determine the work done by the net external force acting on the skier.
Step 1
3 \, \text{kg}$, the initial speed $v_i = 6.10 \, \text{m/s}$, and the final speed $v_f = 11.3 \, \text{m/s}$. We are asked to find the work done by the net external force acting on the skier. Show more…
