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 m/s^(2)

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).

F/a = m

m = (58.8 kgxxcancelm/cancels^(2))/(9.81 cancelm/cancels^(2))

m = 5.99 kg
