Uncertainty#

A steel ball (mball = (31.6 $$\pm$$ 0.02) g) is shot from a mini-launcher on its medium setting, through horizontal photogates spaced (0.1 $$\pm$$ 0.002) 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

0.0258

Trial 2

0.0256

Trial 3

0.0252

Trial 4

0.0255

Trial 5

0.0253

Trial 6

0.0252

Trial 7

0.0253

For this problem, keep one significant figure in the calculated uncertainty and the appropriate number of significant figures in the calculated average time interval.

Part 1#

Calculate the average time interval.

Please enter in a numeric value in s.

Part 2#
