Free Response Review - Chapter 1

The motion graph represents a car on a straight-line track.
-
(a) Describe what happened to the car at t = 1s.
(b) When is the car accelerating the most? Explain how you know.
(c) What is the car's acceleration during that interval?
(d) How far did the car travel between t = 5s to t = 7s?
(e) Plot the car's acceleration versus time.

1. For each of the motion graphs shown above, describe, in detail, what the motion would look like.

2. For each x-t graph shown above, create the corresponding velocity and acceleration versus time graphs.

3. For each v-t graph shown above, create the corresponding x-t graph.

4. At a local football game (let's just say Carrick), a running back flattens a linebacker and continues running at a constant velocity of 10.5 m/s. The instant the linebacker hits the ground, he gets back up and starts running from rest to tackle the running back. If the linebacker accelerates at 1.9 m/s^2, how much time will it take to catch the runner? How far will they have traveled from their original position?

Homework - 8/31/10

The diagram shown above represents two airtrack carts that are about to collide. Cart A is moving and cart B is at rest. After the collision, Cart B's position was marked every 0.1 seconds and is also shown above.


a. Based on the data given for Cart B's position create an accurate position-time graph.

b. Create a general velocity-time graph that represents Cart B's motion. You may reference the x-t graph to help create the velocity graph. (No scale needed)

c. Shade the area under the curve for the v-t graph, state what it represents, and explain what value it should have.
