A net force of 18 N is exerted on a book which accelerates at 8m/s² determine the mass of book

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.
