Chapter 2, Problem 10PQ

As shown in Figure 2.9, Whipple chose a coordinate system that was different from Crall’s. There are many possible coordinate systems that can be used to analyze the motion of the cart. For example, a third student (Yoon) chose to place the origin of her coordinate system at position A (the) cart’s initial position) and use a southward-pointing y axis as her positive axis.

1. a. Use the distance information given in Table 2.2 to make a new table that gives the cart’s position at each of the 16 times according to Yoon’s coordinate system. Hint: A sketch similar to Figure 2.9 is a good place to start.
2. b. Use the data in your table to make a new position-versus-time graph. Hint: CHECK and THINK about your graph by comparing it with Figure 2.6.
