Homework Statement
What is the error in calculating the y-component of the force created by a hanging mass (m=432.23g) at an angle of 28º? Take g=9.81m/s^2)
Homework Equations
Fg = mg
The Attempt at a Solution
Fg = mg
= (0.43223kg +/- 0.000005kg)(9.81m/s +/- 0.05m/s)
= (0.43223 +/- 0.00115679%)(9.81 +/ 0.5097)
= 4.2358 +/- 0.52359%
= 4.2358N +/- 0.022079 NThis was an example drawn on the board. How do you get from line 3-4, and 4-5? I do not know how to calculate 0.52359%, and when I try to calculate the 5th line, I do not get an answer of 0.022079. Please help! Thanks. :)
