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.

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

    F = ma

    F = force, m = mass, a = acceleration

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

    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.

    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.

    a = F/m

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

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

    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.
