You take a jog in the morning as part of your routine exercise. A colleague uses a coordinates system where the motion is parallel to the x-axis and to the right is the +x direction. The colleague makes measurements of your motion and constructs a graph of velocity as a function of time. Determine the distance you covered in the first 3.0 s and from t = 2.0 s to t = 6.0 s.

• A. s (t = 0-3.0s) = 7.5 m
  s (t = 2.0s-6.0s) = 4.0 m
• B. s (t = 0-3.0s) = -7.5 m
  s (t = 2.0s-6.0s) = 0 m
• C. s (t = 0-3.0s) = -7.5 m
  s (t = 2.0s-6.0s) = 4.0 m
• D. s (t = 0-3.0s) = 15 m
  s (t = 2.0s-6.0s) = 8.0 m

Answer: (A)
