A crate of mass 20 kg is pushed up a frictionless ramp by a person as shown in the figure below. Calculate the work done by the person in pushing the crate a distance of 15 m as measured along the ramp. Assume the crate moves at a constant velocity.

  • physics -

    The work done = Force X displacement in the direction of the force.

    The sum of forces in the horizontal direction is mgSin(of the angle)- F = 0

    The force acting, F = mgSin(of the angle).
    The Work done by this force = mgSin(of the angle) X 15 meters

    The Work done = 20 X 9.8 X Sin(of the angle of inclination of the ramp) X 15
