2. You want to use a wheelbarrow to move a pile of dirt. You can comfortably apply 650 N of force on the handlebars. The horizontal distance between you and the front wheel is 1.4 m. The horizontal distance between the stuff in the wheelbarrow and the wheel is 0.5 m. The weight of the wheelbarrow is 80 N. A. What is the weight of the dirt you can carry? B. The total weight you are lifting up (the weight of the wheelbarrow plus the weight of the dirt) is more than what you can lift by yourself! Where did the \"extra force\" come from
