Question

3. Calculate: When a force is exerted over a distance, work is done on an object. Work is measured in joules (J) and is equal to the product of force and distance: W = F • d. For each pulley system, calculate the input work (input force • input distance) and the output work (output force • height). Units of work are newton-meters, or joules (J).
