Answer:

14 m/s^2

Step-by-step explanation:

We have to use the equation F=ma because the question is a Newton's second law question.

First, list known values

F (force) = 70 N

m (mass) = 5 kg

a (acceleration) = ? (we have to solve for this)

Second, plug in known values into equation.

F=ma

70=5a

Third, solve. To solve this all you have to do is divide both sides by 5

70/5=5/5a

Fourth, your answer will be 14 meters per second squared (m/s^2)

I hope this answer helps and have a great day!
