You pull upward on a stuffed suitcase with a force of 118 N, and it accelerates upward at 0.765 m/s2.

What is the mass of the suitcase?

I tried to find the mass and got the mass being 90.27kg but that isn't right. Can someone explain how to find the mass.

Would you use sigma Force = mass x acceleration, because that is what i used?

If you used F = ma, you should have got

m = F/a, but that is not what you did. Therefore you made a mistake.

118/(0.765) = ____

When I divided 118/(.765) I got 154.2 kg.

That answer however, differs from the correct answer by orders of magnitude.

To find the mass of the suitcase, you can use Newton's second law of motion, which states that force is equal to the mass multiplied by the acceleration:

Force = mass * acceleration

In this case, you have the value of force, which is 118 N, and the value of acceleration, which is 0.765 m/s^2. To find the mass, you need to rearrange the equation to isolate the mass:

mass = Force / acceleration

Substituting the given values into the equation:

mass = 118 N / 0.765 m/s^2

Calculating the value:

mass ≈ 154.25 kg

So, the mass of the suitcase would be approximately 154.25 kg, rather than the value you obtained.

It's possible that you made an error in your calculations or used incorrect values. By following the steps outlined above, you should be able to find the correct mass of the suitcase.
