1. The figure shows a graph of the position of a moving object as a function of time. What is the velocity of the object at each of the following times?
a) At t = 1.0 s
b) At t = 2.5 s
c) At t = 4.0 s
d) At t = 5.5 s
e) What is the average velocity of the object from t = 0 s to t = 4.0 s?
f) What is the average velocity of the object from t = 0 s to t = 6.0 s?
