Report

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.

so we will use the work energy principle. Work net is equal to Delta K, and that is what we have to figure out. So Delta K is 1/2 and times VF Square minus. We initial squared and that's equal to 1/2 times The mass is 70.3 kilograms, and then the final speed was 11.3 squared minus. The initial speed is 6.10 squared. So grabbing calculator pushing some buttons, Give me the word networked on a 3.18 times 10 to the power three jewels.
