I'm trying to solve a Physics problem. I already got the answer correct but I'm unable to do the uncertainties. Can someone please explain how to do in this case?
These are the variables used.
g = 9.802 m/s2 +/- 0.0005 m/s2
m2 = 951.0 g +/- 2.3 g
θ = 31.90º +/- 0.07º
And this is what I need to do (only thing left is uncertainties):
total weight on hook 2:
w2 = 9.32 N +/- ____ N
(9.32 = 0.9510 * 9.802)
magnitude of the force on hook 1:
F1 = 7.91 N +/- ____ N
(7.91 = 9.32 * cos(31.90))
magnitude of the total force on hook 3: F3 = 4.93 N +/- ___ N
(4.93 = 9.32 * sin(31.90))

The uncertainties need to have 3 significant digits
