Assume that you have a load cell (such as used in 221 lab) that produced the outputs shown in the table at the right for the conditions described.

An air cart is constrained by a spring on each end such as done in lab. When displaced 10 cm to the right and released at rest, it required 0.32 s to first pass its equilibrium position.

In the first experiment of the semester, you were asked to analyze the motion of a cart on an inclined air track. The raw data consisted of spark marks left on a piece of waxed paper by each electrical pulse of a spark generator operating at a rate of 10 Hertz. Assume you followed the procedure much as described, determined the acceleration of the cart and, from this, determined a value for the acceleration of gravity in Ames of only 2.43 (m/s)/s! You then notice that you inadvertently had set the generator to operate at a rate of 20 Hertz, not 10 Hertz as directed. If this had been your fate, what would have been the most reasonable course of action for you, given the value of your time and the reason for performing the measurements. A) Tell my instructor that the generator was my lab partner's responsibility, since she was doing everything anyway. B) Set the generator to 10 Hertz, erase the values in my data table, and repeat the experiment. C) Beg for mercy, and then go home and have a beer. (::§E> In a way, I did the experiment with a clock that was fast by a factor of two. The purpose of the experiment was to observe the approximately constant acceleration of the cart. I would make notes to the readers of my report to just multiply all velocity values by 2, and all acceleration values by 4 to obtain the actual experimental values. (I would also adjust a few key ones myself.) Then I would go home and have a beer or a cup of tea. E) ‘At 20 Hertz, we would get an extra spark between each spark produced by a 10 Hertz rate. Hence, I would remeasure the original spark tape, ? ignoring every other spark, and redo the data table columns and graph, usin m eraser where necessar . git/«lasts 04: 5:6) q, grager is a. ho-Yw. #5.
