The textbook has a mass of **5.99kg.**

#### Explanation:

Because we are on earth the acceleration due to gravity will have a value of **9.81**

Now to fully answer the question we will have to use Newton's 2nd law of motion equation:

We know the acceleration and force so all we have to do is solve for m by rearranging the equation:

(I'm going to change Newtons into this from so I can cancel out certain units, it means the same thing).
