Textbook Question
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.
- 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.
- 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.

A plane flying at 78.2 m/s [W32°S] takes 42 seconds to change its velocity to 78.2 m/s
[S32°E].
a) Solve for the change in velocity of the plane algebraically, resolving vectors into their x- and
y-components.
b) What was the average acceleration of the plane over this time interval?
c) Explain why the speed of the plane didn't change and yet the plane underwent
acceleration.
