You are trying to lose weight by working out on a rowing machine. Each time you pull the rowing bar (which simulates the "oars") toward you, it moves a distance of 1.32 m in a time of 1.22 s. The readout on the display indicates that the average power you are producing is 53.3 W. What is the magnitude of the force that you exert on the handle.
Power = F*v
where F is the force, v is the speed
53.3 = F * (1.32m/1.22s)
