You are working out on a rowing machine. Each time you pull the rowing bar (which simulates the oars) toward you, it moves a distance of 1.2 m in a time of 1.7 s. The readout on the display indicates that the average power you are producing is 89 W. What is the magnitude of the force that you exert on the handle?

The force exerted on the handle of the rowing machine is : Force = 126.08 Newtons

Explanation:

since power is described as rate of doing work,

therefore,

work = power x time = 89 x 1.7 = 151.3 Joule

Hence, the total work done is 151.3 Joule

Now, using the formula for work done to calculate the final force

Work = Force x Distance

Force = 126.08 Newtons is the force exerted on the handle.
