Work is the force-distance product in algebraic terms simply.

1) David is moving stuff out of house for spring cleaning. He encounters a heavy box full of old Christmas decorations. It was too heavy for him to carry so he pushed it with a force of 240 N resulting a work of 3400 joules across the carpet out the door. How far did he pushed the box?

2) Christine is holding onto twelve books on her hands in a distance of 3 meters with a work of 250 joules. What was the force she was using?

3) Jennifer and I are painting our new room in celebration of not sharing our room with our little brother anymore. I am painting the first wall with a force of 350N and covered 5 meters of it. What was the work in result?

4) A 10 kg object experiences a horizontal force which causes it to accelerate at 5 m/s2 , moving it a distance of 20 m, horizontally. How much work is done by the force?

5) A 10 kg weight is suspended in the air by a strong cable. How much work is done, per unit time, in suspending the weight?
