  1. We need to know the slope of the ramp, if friction is important, and if the object is on earth.

  2. I think we have to assume friction is not important and the object is on earth.

  3. ok
    weight = m g = 9.81 m

    9.81 m sin (Theta) = 215 N

    where Theta is the angle of the ramp up from horizontal
