Each time you pull the rowing bar (which simulates the oars) toward you, it moves a distance of 1.25 m in a time of 1.6 s. The readout on the display indicates that the average power you are producing is 88 W. What is the magnitude of the force that you exert on the handle?

Answer 1

here,

the displacement , s = 1.25 m

time interval , t = 1.6 s

the average power , P = 88 W

let the magnitude of the force exerted be F

Power = F * s /t

88 = F * 1.25 /1.6

solving for F

F = 112.6 N

the magnitude of the force exerted is 112.6 N
