6. The horizontal distance vs time graph of the center of mass of a runner is represented by the following equation. (1t-6t-15t +40) a) Plot the graph from t=0 sec to t-6sec. b) What is the equation that represents the velocity vs time graph? c) Plot the velocity vs time graph from t=0 to t-6 sec d) When is the slope of the position verse time graph negative? Between what times? e) When is the slope of the position vs time graph positive? Between what times? f) What is the instantaneous velocity at t=3 seconds? g) What is the average velocity from t=0 sec to t-6sec? - h) What is the total distance traveled from t=0 sec to t-6sec? i) What is the displacement from t=0 sec to t-6 sec? j) Is this constant acceleration for this problem? Why or why not? 6. The horizontal distance vs time graph of the center of mass of a runner is represented by the following equation.
