2. neatly written on your excel sheet after printing or on a separate sheet of paper (do not
type into excel worksheet): what is the equation for determining the uncertainty in in
terms of the value t and its uncertainty st?
3. calculate the absolute uncertainties of the and terms.
4. calculate the resulting absolute and relative uncertainties of the time term
5. if the measurement of the length (l) is found to be (0.000520.1)m, what would the
corresponding absolute and relative uncertainty be for the l' term?
6. if the measurement in the value of ar was determined to be (0.1025+0.0005)m, what
would be the confidence interval for the acceleration?
7. given that the acceleration due to gravity (g) is the value 9.80m's. what angle is the
track inclined at?
