Homework Help: Determining the frictional resistance.

  1. Jan 2, 2010 #1
    How would you determine the frictional resistance between an inclined plane and cart (with wheels) when you are pulling the cart with a spring scale along the plane when you know:
    mass of cart, vertical height of plane , displacement (hypotenuse of inclined plane), applied force needed to drag the cart on inclined plane, work input: Fd and work output: mgh?

    Is the cart pulled at a constant velocity? probably so...

    Do you know how to find the force required to pull the cart at a constant velocity if the plane was frictionless? Not an experiment, just done on paper?
