Chapter 2, Problem 1P
Figure P2.1 shows a motion diagram of a car traveling down a street. The camera took one frame every second. A distance scale is provided.
Figure P2.1
a. Measure the x-value of the car at each dot. Place your data in a table, similar to Table 2.1, showing each position and the instant of time at which it occurred.
b. Make a graph of x versus t, using the data in your table. Because you have data only at certain instants of time, your graph should consist of dots that are not connected together.

What is a, b, and c?
One afternoon, a student was going home after attending a calculus class. For this reason, the student orders an online motorcycle taxi through the application. At the time of ordering, the online motorcycle taxi is in the position s = 2t² + 2t+4, where t is in units of time and s is in meters.
a. Determine the average speed of the online motorcycle taxi at intervals of 3 minutes to 5 minutes.
b. Determine the time when the instantaneous speed of the online motorcycle taxi is exactly the same as the average speed.
