Name: Date: Block: Part 3: CALCULATING MECHANICAL WORK AND POWER. Mechanical work occurs when a parallel force displaces an object. Power is defined as the rate at which work is performed. Calculate work, force, displacement or power. W = F .d W Joules = N . m Watts = /s Joseph sweeps his sidewalk with a broom. Joseph pushes a pile of dead leaves for distance of 3 meters using a force of 2.0 N. It takes Joseph 12 seconds to push the leaves. Calculate the mechanical work performed on the leaves. Report your answer in Joules. Calculate the power used to push the leaves. Report your answer in Watts A tractor pulls a hay wagon with a force of 500 N for a distance of 2000 meters. It takes the tractor 5 minutes to pull the hay wagon. . Calculate the work performed on the hay wagon. Report your answer in Joules. Calculate the power used to pull the hay wagon. Report your answer in Watts. A backhoe pushes a rubbish pile with a force of 1200 N for a distance of 400 meters. It takes the backhoe 30 seconds to move the rubbish pile. Calculate the work performed by the backhoe on the rubbish pile. Calculate the power of the backhoe pushing the rubbish pile. Joseph sweeps his sidewalk with a broom. Joseph pushes a pile of dead leaves for distance of 10 meters. He performs 35 Joules of work. Calculate the force Joseph uses to push the broom and leaves. Report your answer in Newtons.
