A swimmer moves through the water at a speed of 0.45 m/s. The drag force opposing this motion is 124 N. How much power is developed by the swimmer?Select one:A. 55.8 WB. 275.0WC. 874 WD. 457 W |

Answer» to OBTAIN power developed by the swimmer (p), substitute 124 NEWTON for F and 0.45 m/s for v in the equation p=Fvp=(124N)(0.45m/s)p=(55.8 N.m/s)(1w/1N.m/s)p=55.8Wtherefore power developed by the swimmer is 55.8 W |
