Sample Calculations: Mean time=Sum of terms/number of terms=(.66+.59+.66+.66+.60) s/5=.63s Deviation=| time-mean time | = |.66s - .63s|=.03 s Deviation mean= Sum of deviation terms/ number of deviation terms = (.03+.04+.03+.03+.03) s/5=.03s Percentage mean deviation=100*mean deviation/mean time=100*.03/.63=5% Range=v 0x *(-2* y 0 /a y ) 1/2 =66.21 cm / .63s * (-2*73.45cm/ (-980 cm/s 2 ) ) 1/2 =41cm=.41 m Error Analysis (quantitative): Percentage relative uncertainty for timing=5% Percentage relative uncertainty of measuring distance=100*(.004m/1.000m)=.4% Percentage relative uncertainty of measuring height of table=.2% Total percentage of relative uncertainty=5%+.4%+.2%=6% Actual percent difference between calculated and measured range =100*(.41m-.45m)/(.41m+.45m)=-5% Error Analysis (qualitative): There was a significant difference between my calculated and measured rangers. The percent mean deviation for my range measurements was also less than that for my time measurements. This indicated that my technique for releasing the marble on the ramp was more
