Problem

A constant force of 850N pushes a 150kg mass up the inclined plane shown below. The mass moves at a uniform speed of 3m/s.
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 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
