start with cosTheta
uncertainity is diff between Cos(23.5)and cos(.5)= .5sin23.5=.199
now it is squared, so double it.
error is appx 0.4
now in the expression, it is multiplied by 4d, so add the error in 4d or4*.05
now adding all the errors... +-.6
d1 = 2.53 cm +/- .05 cm
d2 = 1.753 m +/- .001 m
0 = 23.5 degrees +/- .5 degrees
v1 = 1.55 m/s +/- .15 m/s
Using the measured quantities above, calculate the following. Express the uncertainty calculated value.
Z = 4d1 (cos (0))^ 2
