Asked by Robert C

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.
