1. The graph below represents a position function s(t) for an individuals motion over time. Let the positive distance represent the east direction and the negative represent the west direction. s (1) 2 4 5 6 1 -2 a. When is the individual not moving? Briefly explain how you know. [2A, 1T] b. State the time interval(s) when the individual is speeding up. Briefly explain how you know. [2A, 1T] c. State the time interval(s) when the particle is moving to the left. Explain how you know. [2A, 1T] d. State the time interval(s) when the particle is moving away from the origin. Explain how you know. [2A, 1T] e. Determine the time(s), when acceleration is zero. Explain how you know [1A, 1T]
