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?

Respuesta :

Answer:

 P = 75 W

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,

[tex]Power =\dfrac{Work\ done}{time}[/tex]

[tex]P =\dfrac{1200}{16}[/tex]

 P = 75 W

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