a libraian lifts a box of books that weighs 93 N a distance of 1.5 m. How much work does he do?

Answer

To calculate the work done by the librarian, we need to use the formula:

Work = Force × Distance

In this case, the force exerted by the librarian is the weight of the box, which is given as 93 N, and the distance over which the force is applied is 1.5 m.

Using the formula, we can calculate the work done:

Work = 93 N × 1.5 m

Work = 139.5 N·m

Therefore, the librarian does 139.5 Joules (J) of work.
