4) Refer to the velocity time graph below to answer the following questions. Interval A
is from t=0-2s, B from 2-5 s, C from 5-7 s, D from 7-9 s and E from 9-10 s.
a) Describe the motion of the object for each of the 5 intervals. You may use
speeding up, slowing down, going at constant velocity, to the left or to the right.
b) When does the object turn around?
c) Find the acceleration of the object during interval A and interval D.
