Question

4. A net force of 15 N is exerted on a book to cause it to accelerate at a rate of 5 m/s2. Determine the mass of the

book.
a. 0.33 kg
b. 2 kg
c. 3 kg
d. 45 kg

Answer 1

3 kg

Step-by-step explanation:

The mass of an object given it's force and acceleration can be found by using the formula

`m = (f)/(a) \\`

f is the force

a is the acceleration

From the question we have

`m = (15)/(5) = 3 \\`

We have the final answer as

3 kg
