In the old days when we still used motor-less lawn movers, the mover was a roller with blades and a handle by which we would pull or push the mover. As the mover is pushed, the roller with blades would turn and you could cut the grass. One particular model of the mover had a roller of diameter of 19 inches. The roller weighs 200 lb. What is the minimal force you need to use to pull the roller over a 2 inch tall curb if the handle makes 30 Degree angle with the horizontal?
