Question

A climber pulls herself 8 meters upwards with a force of 150 Newtons. If it takes her 16 seconds to cover the 8 meters, how much power is she using?

Answer 1

P = 75 W

Step-by-step explanation:

given,

Distance, L = 8 m

Force,F = 150 N

Time, t = 16 s

Work by the climber

Work done = Force x displacement

W = F. L

W = 150 x 8

W = 1200 J

We know,

`Power =(Work\ done)/(time)`

`P =(1200)/(16)`

P = 75 W

Hence, Power climber is using to climb is equal to 75 W.
