Please help generate 2 graphs for positions vs time and velocity vs time based on the data given in the problem .

Eric dreams about walking toward and away from a motion detector and wakes up in a cold sweat wondering if he can graph his motion. In his dream, he starts by walking briskly away from a motion detector at 3.0 mfs (in a positive direction). He does this for 4 seconds. He almost instantly stops and for the next 3 seconds he stands still. Then for 3 seconds he walks toward the motion detector at 2.0 mis (a negative direction). Graph the position versus time and velocity versus time graphs you would expect to see. (10 points)
