A crane lifts 50 Newtons 2 meters. How much work is done
Nikitich [7]

Answer:

100 Joules

Step-by-step explanation:

We use the definition of Work as the force applied multiplied by the distance the object was moved. In our case the force exerted is 50 N, over a distance of 2 meters, therefore:

Work = F * d = 50 N * 2 m = 100 N*m = 100 Joules

The SI unit for Newton times meter is called "Joule".
