A speed boat requires 80 kW to move at a constant speed of 15 m/s.What is the resistive force of the water at this speed?
A)2 700 N
B)5 300 N
C)6 500 N
D)7 700 N

Question

Quizplus · Accepted Answer

The power required to overcome the resistive force is given by the formula Power = Force × Velocity. Rearranging gives Force = Power / Velocity. Substituting the given values, Force = 80,000 W / 15 m/s = 5,333.33 N, which is closest to 5,300 N.
