5. An object is traveling at 20 m/s, but is accelerating at -5 m s2. After six seconds the object begins to slow and has come to a stop five seconds later. Draw graphs of position, velocity and acceleration versus time (each on separate axes) for this object. Be quantitative. Specify the position, velocity, acceleration and time tor point(s) when the object has stopped.
Question 2 A car is traveling to the left at 20 m/s and it is accelerating to the left at a constant rate. After 5 seconds of time, the car is traveling to the right at 5 m/s. a.
