High School Did I Neglect the Skier in the Resistive Force Calculation?
Hi, Imagine a boat with a skier behind it (connected with a rope). Mass of boat=2000Kg Mass of skier=80Kg At 20m/s the boat engine has a power output of 140kW Calculate the total resistive force. Power=FxV 140000W=Fx20m/s F=7000N Is the answer right ? I doubt my answer, even if its really...
