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.

Plus and minus signs are used in one-dimensional motion to indicate direction. What is the sign of an acceleration that reduces the magnitude of a negative velocity? Of a positive velocity?
Sketch the acceleration-versus-time graph from the following velocity-versus-time graph.
A pedestrian is running at his maximum speed of 6.0 m/s to catch a bus stopped at a traffic light. When he is 15 m from the bus, the light changes and the bus accelerates uniformly at 1.00 m/s2. Does he make it to the bus? If so, how far does he have to run in order to catch it? If not, how close does he get? Use sketches on velocity vs time and acceleration vs time graphs to make your case.
An object is moving in the air (defying gravity) so that its height after t seconds is given by ℎ(t)=18sin(t)cos(t)+8t meters. (If you graph this function, you can see it's moving up and down, but going higher and higher as time goes on.) a) At what time, t, does the object first change direction from going up to going down? b) What is the acceleration (m/s^2) of the object at that same time?
How can you tell if a motion situation is acceleration or constant velocity just by looking at a distance-time graph??

A Turtle is moving with a constant acceleration along a straight path. He starts his stopwatch as he passes afence post and notes that it takes him 10.0 s to reach a pine tree 10.0 m farther along the path. As he passes the pinetree, his velocity is 1.2 m/s. How far from the fence post was he when he started? Use diagrams as part of your solutionand verify that your answer is correct.
