Question
A force of 165 N is needed to keep a small boat moving at 2.57 m/s. What is the power required to keep the boat moving at the steady speed?
>> I understand that P=Fv but I don't understand the second question.
If the resistive force of the water increases with the square of the speed, what power is required if the speed is increased by 50 percent?
