## Question

a book has a mass of 50 kg and an acceleration of 5 m/s^{2}. what is the force on the book?

### Final Answer

We will use the formula (F = ma) to obtain the force (F = ma = 50 x 5 = 250N) on the book as 250 Newtons which is our final answer.

### Explanation

**Data**: The information revealed in the question that will help us solve the problem

Mass of the book, m = 50 kg

Acceleration of the book, a = 5 m/s^{2}

**Unknown**: What we need to find

The force on the book, F = ?

**Formula**: The equation we need to solve the problem

We need to apply the equation of the Newton’s second law to solve this problem

F = ma

#### Solution

We will need to substitute our formula with the data to obtain

F = ma = 50 x 5 = 250 N

Therefore, the force on the book is 250 Newton. You will also need to remember that the si unit of force is in Newton.
