If a person. of. mass. 50. carrying. a mass. of. 60 kg. up to. height. of. 20m. in. 60sec. . Find. the. power. of. person |
Answer» The power of person is 333.3 wattExplanation: The mass of man = 50 kg The load on his head = 60 kg The total mass = 50 + 60 = 110 kg The height covered by this mass h = 20 m The work DONE W = mass x acceleration due to gravity x height THUS W = 110 x 10 x 20 = 22 x 10³ J The power = Work/time Thus power = |
