Data Table for two labs including weights and angles

Calculate Newtons using Newtons = mass(gravity)
FA = .5139 X 9.8 m/s^2 = 5.036 N            

Calculate components. Use Calculations from above then  do Newtons(sin angle) then Newtons(cos angle)

Ax = 5.036 X Cos(0) = 5.036                     Ay = 5.036 X Sin(0) = 0

 The fourth value will be your experimental. Do not use that for the next part.

Dx = 2.096 X Cos(-156) = -1.914                Dy = 2.096 X Sin(-156) = -0.8525

Add together the NEWTONS( cos or sin?)  only of the first three measurements Ax + Bx + Cx + Dx = 0. Replace Dx with Zx. Ax + Bx + Cx + Zx = 0. Use Newtons for Ax, Bx, and Cx, then calculate for Zx for the hypothetical

5.036 + -0.8526 + -2.091  + Zx = 0           0 + 0.7154 + 0.1462 + Zy = 0

          Zx = -2.092                                    Zy = -0.8616 

 Use these values to calculate ZD

Zx^2 + Zy^2 = ZD^2

Then do Inverse tangent (Zy/Zx)

Inverse tangent (-.8616/-2.092) = 22.38922
