Answer:
2.25 kg
Explanation:
Force can be found using the following formula.
Rearrange the formula for
, mass, by dividing both sides of the formula by a.
The mass can be found by dividing the force by the acceleration. The force is 18 Newtons. 1 Newton is equal to 1 kg m/s², so 18 Newtons is equal to 18 kg m/s². The acceleration is 8 m/s².
Substitute the values into the formula.
Divide. Note that the kg m/s² in the numerator and denominator will cancel each other out.
The mass of the book is 2.25 kilograms.
