Question

According to Newton's Second Law, if force equals 17 N and acceleration equals 8 m/s2, what is the mass in kilograms?

Answer as a number, rounded to the nearest thousandth?

Answer 1

The mass is 2¹/₈, or 2.125, kg

Explanation:

We know that force is equal to mass times acceleration, so given a force of 17 newtons and an acceleration of 8m/s², we can say:

`f = ma\\m = f/a\\m = (17\ N)/(8\ m/s^2)\\m = (17\ kg* m/s^2)/(8\ m/s^2)\\m = 17/8\ kg\\m = 2.125 kg`

giving us a mass of 2¹/₈, or 2.125 kg.

Answer 2

2.13kg

Explanation:

fnet=ma

17=m(8)

17÷8 =m

2.13=m
