Aperson weighing 500 n climbs 3 m. how much power is needed to make the climb in 5 sec?

The power needed by the person is 300 W

Explanation:

Power is defined as the ratio of rate of work done by an object.

Mathematically,

where,

P = power of the person

W = work done by the person =

F = force applied by the person = 500 N

d = displacement of the person = 3 m

t = time taken = 5 sec

Putting values in above equation, we get:

Hence, the power needed by the person is 300 W
