calculate power

Question

Calculate the power rewuired to put a mass I'd 120kg at a constant velcoity of 5m/s down a plane. The plane mkes an angle horizontally. The frictional force is 350N.

Answer 1

Mass, m = 120 kg

Constant velocity, v = 5 m/s

Frictional foce , F = 350 N

Power required to put the plane by using the formula:

P = FV

    =  (350)(5)

    =  1750 W

    = 1.75 kW
