Name_________________________ Date: _____________________Course number: _________________Answer Questions 4-6 using the hand timer data:4. Calculate the mean and standard deviation of t. (1 pt)t = ______Δ t = ______5. Find the average acceleration using Equation 3.9. Enter the average time that youfound in Question 4. (1 pt)a = ______6. Using Δ t and a reasonable estimate for the uncertainty in S, find the uncertainty forthe acceleration measured using hand timers. The equation for summing theseuncertainties is below. Show your work and underline the term that is the largest sourceof uncertainty. (1 pt)Δaa=⎛⎛ ΔS⎜⎜⎝⎝ S2⎞⎞⎟⎟⎠⎠2⎛⎛ 2Δt⎞⎞+ ⎜⎜ ⎟⎟⎝⎝ t ⎠⎠Δ S = ______Δ a = ______7. Use Equation 2.1 to calculate g measured using photogates and hand timers. AlsoM1 + M2calculate the uncertainty in each method using the equation: Δg= Δa.M1− M2mCompare your answer from each method to the accepted answer of 9.80392 given insthe introduction.
