Listen You are measuring the average speed of your well-trained dog. The dog runs to the end of a field and back to you. You measure the length of the field, L, and the round-trip time, t, with their uncertainties AL and At, to calculate the average speed of the dog: v = 2L/t. Using the multiplication and division rule for propagation of uncertainties, select the expression for the absolute uncertainty in the average speed. Form: r= xy or r= x/y Rule: Ar/r= Ax/x+ Ay/y A) Av=(2AL/L - At/t)v B) Av=(2AL/L+ At/t)v C) Av=(AL/L+ At/t)v D) Av=(AL/L- At/t)v E) Av=(AL/L+ At/t)

Consider the following hypothetical results for an experiment similar to the one you designed and conducted this past week. Refer to Part 2 of the Student Lab Guide, (page 34 on propagation of uncertainty, and pages 53-56 on statistical significance of your results) for assistance. Ben and Jerry tested the dependence of the acceleration of a cart on the net force applied to that cart (a=F/m). The cart mass was known to be 0.600 kg with negligible uncertainty. They plotted acceleration versus force and found the slope of their graph to be 1.70 +/- 0.02. Answer the following questions: (a) What are the units of their slope? Why? (b) What is the expected value of their slope? Why? (c) Is their experimental result consistent with this expected value? Why or why not?
