Question

A horizontal force of magnitude 23.1 N pushes a box along a horizontal floor at a constant speed of 7.27 m/s. The velocity of the box and the force are in the same direction.

What is the power supplied by this force, in watts?
force * distance / time = power ... N * m / s = W
P = F*(d/t) = F*V = 23.1 * 7.27 = 168 J/s = 168 W.
