Problem

A constant force of 850, start text, N, end text pushes a 150, start text, k, g, end text mass up the inclined plane shown below. The mass moves at a uniform speed of 3, start text, m, slash, s, end text.
A ramp has a constant upward slope from left to right. The vertical height at the right end of the ramp is labeled two meters. A rectangle labeled M is shown going up the ramp. An arrow parallel to the ramp points upslope to the rectangle. It is labeled F push.
Determine the power the force develops as it pushes the mass up the ramp.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
start text, W, end text
