2. A man uses 125 N to push a block of wood up a ramp at constant velocity of 3.6 m/s. What is his power output?


Given: Formula: Solution:

[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The power of an object exerting a force F at a velocity v is given by

[tex]\boxed{P = Fv}[/tex]

where:

P = power

F = force

v = velocity

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for P

P = Fv

P = (125 N)(3.6 m/s)

[tex]\boxed{P = \text{450 W}}[/tex]

Therefore, the amount of power output is 450 W.
