Draw a motion diagram of an object that has:

1. Positive velocity and negative acceleration.

2. Negative velocity and negative acceleration.

Consider the velocity vs time graph above.

3. Describe motion in words (Assume object begins at origin at t = 0.)

4. Draw the acceleration versus time graph.

5. Draw the distance versus time graph. (Assume objects begin at origin at t = 0.)

6. George finally got up the courage to go sky diving. He took his stuffed teaddy bear named Harry. (George never goes anywhere without Harry). But as the ground approached at a constant rate of 20 m/s, George began to panic and dropped Harry. Trying to calm himself down, he measured the time it took Harry to splatter all over the pavement below. He noticed it was 10 seconds. (Ignore air resistance, use g = 10 m/s2). Considering the fact that a descent exceeding 12 m/s is usually fatal, how long did George have to live after Harry's impact?

A ball is thrown vertically upward.

7. Draw a motion diagram from the time it leaves the throwers hand until it strikes the Earth.

8. Determine direction of acceleration : at point A half way up, at point B top of flight, at point C half way down and draw an arrow representing it on your motion diagram at each of the points.

9. A = 3i - 2j, vector B has magnitude 10 and makes an angle of 37° with the positive x axis.

Graph A and B and determine A + B Graphically.

10. Find the Bx and By algebracally.

11. Find the magnitude and direction of C = A + B.
