Knight et al., chapter 2

2. which x vs. t graph described my motion most closely ?

4. which v vs. t diagram represents the motion diagram above ?

5. which x vs. t graph represents the v vs. t graph above ?

6. soccer problem

7. time for the first problem:
At t = 0s a soccer forward is 15 m from the goal when he hits the ball towards the goal. At t = 0.5s the ball passes the last defender who is 5m in front of the goal. How much time does the goalie have to react?

8. OK, here’s another one:
Alan leaves Los Angeles at 8:00 AM to drive to San Francisco, 400 mi. away. He travels at a steady 50 mph. Beth leaves Los Angeles at 9:00 AM and drives a steady 60 mph.
who gets to San Francisco first ?
How long does the first to arrive have to wait for the second ?
