Worcester Polytechnic Institute PH 1111, Term A, 2007 Experiment #2 Lab Worksheet 1. As described in ReadMeFirst,Exp2,Part2, determine the average acceleration of the cart on the inclined track by fitting a straight line to the v x vs. t graph, using reasonably equal parts of the UP and DOWN portions of the cart travel. Express below in proper form, including uncertainty and units. Where indicated also express the ratio of the uncertainty to the slope- value as a percentage. 2. Repeat for the acceleration value for the UP portion of the v x vs. t graph. 3. Repeat for the acceleration value for the DOWN portion of the v x vs. t graph. 4. Determine the slope-angle of the track from the average acceleration above plus the fact that in Worcester, MA, the straight-down acceleration value is 9.80 m/s 2 . Then determine the uncertainty in the slope angle as follows: determine the slope-angle values for the acceleration-PLUS-uncertainty and then the acceleration-MINUS-uncertainty; calculate the differences between those angles and the angle
