Question

A student with a mass of 62.0 kg walks up a flight of stairs with a height of 3.40 meters. If it takes him 7.00 seconds to get to the top, how much power did he generate?

Answer 1

Answer:

Power generate by generator = 265 W (Approx.)

Explanation:

Given:

Mass of student = 62 kg

Height of stairs = 3.4 meter

Time taken = 7 second

Find:

Power generate by generator

Computation:

Power = Force x [Distance / Time]

Power = [Mass x gravitational acceleration] x [Distance / Time]

Power = [62 x 9.8][3.4/7]

Power = [607.6][3.4/7]

Power = 265.12

Power generate by generator = 265.12

Power generate by generator = 265 W (Approx.)
