          Instantaneous Velocity: example problem
A train moves slowly eastward
along a straight portion of track.
Its position as a function of time
is shown in the graph.
Find:
(a) The average velocity for the
total trip.
(b) The average velocity for the
first 4.00 s.
(c) The average velocity from $t = 4.00$ s to $t = 8.00$ s.
(d) The instantaneous velocity at $t = 2.00$ s.
(e) The instantaneous velocity at $t = 9.00$ s.
(a) 0.833 m/s [E] (b) 1.00 m/s [E] (c) 0 m/s (d) 1.00 m/s [E]
(e) 0.75 m/s [E]
