A 100-n boulder is sitting on a shelf 0.5 meters above the floor.

If the boulder is moved vertically to another shelf 3.0 meters above the floor, how much work has been done on the boulder?

• Physics -

work=mg*changeinHeight.

Are you thinking these out, or am I doing if for you?

• Physics -

I have the formulas - I just want to make sure I am answering them correctly.
