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.
Suppose that a car traveling to the east (+x direction) begins to slow down as it approaches a traffic light. Which statement concerning its acceleration must be correct? Select one: a. Its acceleration is in the +x direction. b. Its acceleration is in the -x direction. c. Its acceleration is zero. d. Its acceleration is decreasing in magnitude as the car slows down.
1. A car is travelling towards the start line and the timer starts timing when the car crosses the start line. When the car crosses the start line, it is travelling at 5 m.s1. The car maintains its speed for 3 seconds then speeds up to 8 m.s1 in 4 seconds. It maintains this speed for 1 second then brakes hard and comes to a rest in 3 seconds. 10 9. 8. 7 3 2 1 0. 0 1 2 3 4 7 8 9 10 11 Time (s) a) What is the instantaneous velocity of the car at t = 7 s? b) What is the displacement? c) What is the average velocity of the car for the journey? 5 4- Velocity (m/s)
2. Frankie and Rosie take a trip in a car from one town to the next. During the trip several different average speeds are driven based on traffic. Frankie drives for 16.4 miles at 22.0 m/s, 14.5 miles at 26.0 m/s, and 30.2 miles at 18.0 m/s. As part of this trip Frankie and Rosie stop to eat dinner at a diner for about 35.0 minutes.
