Question: The motor of a ski boat generates an average power of 7.20 x 104 W when the boat is moving at a constant speed of 11 m/s. When the boat is pulling a skier at the same speed, the engine must generate an average power of 8.00 x 104 W.
Part A: What is the tension in the tow rope that is pulling the skier?
I need help to find the tension in the tow rope that is pulling the skier.
