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
