Question:

Wall-E does 750 J of work pushing a block of rubbish 15 m. Calculate the force he is pushing with.

Solution:

By the definition of the work done we have:

$$W = F s,$$

here, W is the work done by Wall-E, F is the force acting on a block of rubbish, s is the distance.

From this formula we can calculate the force acting on a block of rubbish:

$$F = \frac {W}{s} = \frac {7 5 0 J}{1 5 m} = 5 0 N.$$

Answer:

$$F = 5 0 N.$$
