You need to pick up a book off the floor and place it on a tabletop. You expend 1.56J of energy to lift the book with a force of 300N. What is the distance?

Work done = Froce × distance

Now, keeping this formula in mimd, we can find the distance as follows;

= 1.56 = 300 × distance

= 1.56/300 = distance

= 156/30000 = distance

= 0.0052 m = distance

Lets convert it into cm so that you don't get troubled seeing it :)

= 1 m = 100cm

= 0.0052 × 100

= 0.52 cm
