Question

(c) If the person stays at a normal walking gait of 1.4 m/s but turns in the negative direction during the walk, is there an acceleration? Yes No Not enough information (d) Let's say that you did not change directions as in part (c). Now, you have a boost of motivation and increase your speed to 2.2 m/s over a period of 8 seconds. Calculate your average acceleration over this time period. Be sure to watch direction and units. The average acceleration is 0.1 m/s² (e) Lastly, you tire and decide to slow down from 2.2 m/s to 1 m/s, and you decrease your velocity over a period of 16 seconds. You are still moving in the forward (positive direction), you have just slowed down. 1. Are you experiencing an acceleration over this slow-down time? Yes No Not enough information 2. If so, calculate your average acceleration over this time period. Be sure to watch direction and units. What does your answer tell you and how does it compare to the scenario? The average acceleration is m/s²
