6. Modeling Motion with Motion Diagrams Create complete motion diagrams (e.g. they should include velocity and acceleration vectors), or interpret the given complete motion diagrams by writing a one or two sentence "story" that might explain the motion for the following situation a. A car accelerates uniformly (1.e. the acceleration is constant) from a stoplight for five seconds, then coasts for three seconds. b. An airplane doubles its speed over a four second time interval
