If you divide the total distance traveled on a car trip (as determined by the odometer) by the elapsed time of the trip, are you calculating average speed or magnitude of average velocity? Under what circumstances are these two quantities the same?
A car travels on a straight, level road. (a) Starting from rest, the car is going 44 ft/s (30 mi/h) at the end of 5.0 s. What is the cars average acceleration in ft/s2? (b) In 4.0 more seconds, the car is going 88 ft/s (60 mi/h). What is the cars average acceleration for this time period? (c) The car then slows to 66 ft/s (45 mi/h) in 3.0 s. What is the average acceleration for this time period? (d) What is the overall average acceleration for the total time? (Note these convenient British unit conversions: 60 mi/h = 88 ft/s, 45 mi/h = 66 ft/s, and 30 mi/h = 44 ft/s.)

Parts (a), (b), and (c) of Figure 2.10 represent three graphs of the velocities of different objects moving in straight-line paths as functions of time. The possible accelerations of each object as functions of time are shown in parts (d), (c), and (f). Match each velocity vs. time graph with the acceleration vs. time graph that best describes the motion. Figure 2.10 (Quick Quiz 2.3) Match each velocity vs. time graph to its corresponding acceleration vs. time graph.
Colonel John P. Stapp, USAF, participated in studying whether a jet pilot could survive emergency ejection. On March 19, 1954, he rode a rocket-propelled sled that moved down a track at a speed of 632 mi/h. He and the sled were safely brought to rest in 1.40 s (Fig. P2.41). Determine (a) the negative acceleration he experienced and (b) the distance he traveled during this negative acceleration.

Consider a car that is initially traveling along a straight stretch of highway at 15 m/sm/s. At t=0t=0 the car begins to accelerate at 2.0 m/s2m/s2 in order to pass a truck. The final velocity is vx=25m/svx=25m/s. Calculate how far the car travels during its 5.0 ss of acceleration. If the car maintains its constant acceleration for a total time of 11 ss , what total distance does it travel? Express your answer in meters.
Ferrari LaFerrari can go from zero to 120 miles per hour in 6.5 seconds. Assuming that it can keep its acceleration constant, how long a distance can it cover in 15 minutes? Express the answer in metric units. (1 mile is equal to 1.61 kilometers) Hint: Obtain the acceleration from the first setence.
