Answer:

The answer is 0.75 m/s²

Explanation:

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

[tex]acceleration = \frac{force}{mass} \\ [/tex]

From the question

mass of backpack = 20 kg

force = 15 N

So we have

[tex]acceleration = \frac{15}{20} = \frac{3}{4} \\ [/tex]

We have the final answer as

0.75 m/s²

Hope this helps you
