soccer problem
![Page 7: PHYS 101 Knight et al., chapter 2. which x vs. t graph described my motion most closely ?](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649d2f5503460f94a06b08/html5/thumbnails/7.jpg)
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?

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 ?
