At 10:17 a.m., you pass a police car at 55 mph that is stopped on the freeway. You pass a second police car at 55 mph at 10:53 a.m., which is located 39 mi from the first police car. If the speed limit is 60 mph, can the police cite you for speeding? а. a. The total time between your two police car sightings was P hours. b. Your average speed between the two police car sightings was 8, mph. c. Can the police cite you for speeding? No, your average speed was less than the speed limit. CYes, since your average speed was more than the speed limit, there must have been somewhere within the 39 mi where you were driving more than 60 mph.

One of the most difficult things to learn in physics is that our everyday language is not always precise enough. For instance, we might say a car is “slowing down”, but that only gives us information abouts velocity, not its acceleration. What can we say about the velocity of a car which has negative acceleration in the x-direction? a. It is slowing down. b. The x-component of its velocity is decreasing. c. The x-component of its velocity is negative. d. It is speeding up. e. The x-component of its velocity is positive. f. The x-component of its velocity is increasing.
