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.

the force required to move the cart is divided by three or 33.33 n.
