## ikshjbdckoj 2 years ago Someone I need help..! If the force of 12 N is applied to an object with a mass of 2 kg, the object will accelerate at 0.17 m/s². 24 m/s². 6 m/s². 12 m/s².

1. ikshjbdckoj

I think there's a formula for this just not sure.

2. mathstudent55

F = ma

3. mathstudent55

F = force, m = mass, a = acceleration

4. ikshjbdckoj

okay so it would look like 12= 12 something? I dont know what that is yet.

5. mathstudent55

F = ma, you have the force and the mass and are looking for the acceleration, so solve F = ma for a. Then plug in the values you have and get a value for a.

6. ikshjbdckoj

Well I kindof understand that but not all the way. I don't understand how to plug in the numbers to the formula. I'm not good at formulas.

7. mathstudent55

a = F/m

8. mathstudent55

a = F/m = 12 N/2 kg = 6 (kg-m/s^2)/kg = 6 m/s^2

Oh lord, thats a lot of working out...

10. ikshjbdckoj

OHHH so is the answer 6???

13. ikshjbdckoj

oh so im right?:) Cause I'm really confused actually.

14. ikshjbdckoj

I didn't work it out like that. I just divided 12/2 got 6 and saw 6 and thought that was the answer.

15. mathstudent55

The answer is 6 m/s^2. An acceleration is given in units of acceleration. In this case the units were meters per second square. Notice that all the choices for answers are in m/s^2.

16. ikshjbdckoj

ohhhhhhhhhh okay... I got it now. Thanks :)

You're welcome.
