The m = 420 gg mass in (Figure) is pushed across the 2.0-m-long cart by a 3.0 N force, starting at the left side. The coefficient of kinetic friction between the mass and the cart is 0.40. The cart's coefficient of rolling friction is 0.020.   How far has the cart rolled when the mass falls off the right side? Express your answer with the appropriate units.
