A librarian lifts a box of books that weighs 93N a distance of 1.5 m. How much work does he do?
work = force * distance
To calculate the work done by the librarian, we use the formula:
Work = Force x Distance
In this case, the librarian lifts a box of books with a force of 93N over a distance of 1.5m.
Therefore, the work done by the librarian is:
Work = 93N x 1.5m
To obtain the answer, simply multiply the force (93N) by the distance (1.5m).
Work = 139.5 Joules
So, the librarian does 139.5 Joules of work when lifting the box of books.
