Explanation:

0.6 metres

Explanation:

Given that,

force on a book = 4.5N

work done = 2.7 J

Distance moved by the book = ?

Recall that work is done when force is applied on an object over a distance. Hence, work = force x distance

2.7J = 4.5N x distance

distance = 2.7J / 4.5N

distance = 0.6 m

Thus, you must have moved the book 0.6 metres far.
