Question

You exert a force of 5.3 N on a book to slide it across a table. If you do 2.5 J of work in the process, how far did the book move?

Answer 1

We will have the following:

`2.5J=5.3N\cdot x\Rightarrow x=(2.5J)/(5.3N)`
`\Rightarrow x=(25)/(53)m\Rightarrow x\approx0.47m`

So, the book moved 25/53 meters, that is approximately 0.47 meters.
