Using the given hoist scenario, what is the work input required to move the hoist horizontally 12 feet with a constant force of 70 pounds?

Explanation:
Work is found by multiplying the force by the distance the object moves in the direction of that force. Here, a constant horizontal force of 70 pounds moves the hoist 12 feet, so the work input is 70 × 12 = 840 foot-pounds. This matches the given distance and force; the other numbers would come from different distances.
