Consider a car moving leftward on the x-axis. when it is at x = 100 m and moving at a speed of 20 m/s, it begins to slow down uniformly until it stops after travelling for 4.0 seconds. a. draw a motion diagram to represent this part of the motion. b. draw two graphs, x vs. t, and vx vs. t. indicate how the given information is used to draw the graphs. c. how far did it travel in coming to a stop from when it first started to slow down?
