A person with a weight of 956 N runs up a 2.41 m staircase. If it takes 4.17 seconds to reach the top, how much power was genera
ted?
1 answer:
Answer: 552.5 watts
Explanation:
Given that,
Weight of man = 956 N
Height (h) = 2.41 m
Time taken (t) = 4.17 seconds
Power = ?
Recall that power is the rate of work done per unit time i.e Power = work/time
Thus, power = (mgh) / t
(Since weight = mass x acceleration due to gravity)
Power = (weight x height)/ time
Power = (956N x 2.41 m) / 4.17s
Power = 2303.96/4.17
Power = 552.5 watts
Thus, 552.5 watts of power is generated.
