a mover uses a ramp to pull a 1000 newton cart up to the floor of his truck 0.8 meters high if it takes a force or 200 newtons to pull the cart what is the length of the ramp

  • physics - ,

    The answer depends upon the amount of friction. If there is no friction, they should have said so.

    In the frictionless case,
    (Force) x (ramp length) = (weight) x (height)

    To approximate frictionless behavior, the cart should have well lubricated wheels.

    200*0.8=160
