Q2. Here is a plot of the velocity vs. time for an car. Take a look at the plot and answer each of the following questions: 1. Describe the car's velocity vs. time. For example..."At the beginning of the plot the car was traveling at a velocity of After seconds of constant velocity the car..." 2. What is the initial velocity of the car and how many seconds does the car travel at this velocity? 1. What distance does the car travel while at the initial velocity? 3. What is the final velocity of the car? 4. During what section of the plot (start & stop times) does the car accelerate? 1. How many seconds does the car accelerate? 2. What is the velocity before the acceleration (vi)? 3. What is the velocity after the acceleration (vf)? 4. Calculate the car's average acceleration over this period. 5. During what section of the plot (start & stop times) does the car decelerate? 1. How many seconds does the care decelerate? 2. What is the velocity before the deceleration (vi)? 3. What is the velocity after the deceleration (V+)? 4. Calculate the car's average deceleration over this period. Velocity (m/s) 22 20 10 16 14 12 10 0 2 6 0 10 12 14 16 Time (s) 20
