Uncertainty#

A steel ball (mball = (32.6 \(\pm\) 0.03) g) is shot from a mini-launcher on its medium setting, through horizontal photogates spaced (0.30000000000000004 \(\pm\) 0.001) m apart. The time interval that the ball spends between these gates is measured in six independent trials to be:

Trial Number

Time between gates (s)

Trial 1

0.0758

Trial 2

0.0758

Trial 3

0.0758

Trial 4

0.0752

Trial 5

0.0752

Trial 6

0.0753

Trial 7

0.0758
