If you travel in a straight line at 50 km/h for 1 h and at 100 km/h for another hour, is your average velocity 75 km/h? If not, is it more or less? Explain.

# 5) There is a high-speed police chase on 1-64! The driver of a police car heading East pulls off into an emergency turn around on 1-64 so that he can turn around and join the pursuit, which is moving on the westward side of the interstate. In order to successfully merge with constant acceleration, the police car starts from rest, moves in a straight line, and has a speed of 24.0 m/s when it reaches the end of the merge lane, which has a total length of 80.0 m. Report answers below to 3 sig figs. A) What is the magnitude of the constant acceleration of the police during merging? B) How much time does it take the police car to travel the full length of the merging lane? C) The traffic on 1-64 is moving at a constant speed of 17.0 m/s. What distance does the traffic travel while the police car is moving the length of the merging lane?

Can a car traveling west simultaneously have an acceleration pointing east? If not, explain clearly why not. If yes, give a clear example of a situation in which it could occur.
