A car is traveling at 73 mi/hr in a 60 mi/hr zone. There is a cop parked 20 ft ahead of you. You slow down at an acceleration of -2ft/sec^2, for a total time of 3 seconds. Do you get a ticket?

Answer 1

If your acceleration is - 2ft/sec2 for 3 seconds, then the change is speed is 6ft/sec

The initial speed is 73mi/hr, which is 107ft/sec. Thus, the speed after 3 seconds is 113ft/sec, and the average speed during the 3 seconds is 110ft/sec. So-----you travel 330 feet.
