1. The problem statement, all variables and given/known data Remember: all answers (including uncertainties) must have three significant digits. For all problems: use the value of g given: g = 9.802 m/s2 0.0005 m/s2. Look at the diagram in the above image. Suppose the total mass of hook 2 is m2 = 951.0 g 2.3 g, and θ = 31.90o 0.07o, and the system is in equilibrium. Find the following quantities, with uncertainties: - the total weight on hook 2. w2 = ___ N +/- ___ N - the magnitude of the force on hook 1. F1 = ___ N +/- ___ N - The magnitude of the total force on hook 3. F3 = ___ N +/- ___ N 2. Relevant equations F = m * a 3. The attempt at a solution w2 = m * g = 0.9510 * 9.802 = 9.32N F1 = 9.32 * cos(31.90) = 7.91N F3 = 9.32 * sin(31.90) = 4.93N I am just unable to solve the uncertainties. Someone else suggested that I use this equation Δf = df/dx*Δx + df/dy*Δy but I don't know how to use it or which values I have to use with it. Can someone please explain how I can do this? I'm really bad at solving uncertainties since I never really understood how to do it. Thank you.
