A particle is moving with a constant acceleration of 4.0 m/s2 . Its speed at t = 1.0 s is 4.0 m/s and at t = 3.0 s it is 12.0 m/s. What is the area under the position-time graph for the interval from t = 1.0 s to t = 3.0 s?
 a. 8.0 m/s
  b. 8.0 m
  c. 12 m
  d. 16 m
  e. 16 m/s2

Question 2

A particle is moving at constant velocity. Its position at t = 1.0 s is 3.0 m and its position at t = 4.0 s is 15.0 m. What is the slope of the position-time graph for this particle?
 a. 0, since this is a constant velocity situation.
  b. 4.0 m/s
  c. 4.0 m/s2
  d. 9.0 m/s
  e. 12 m/s2
