Interpreting Graphics The velocity-versus-time graph for a shut-
tle bus moving along a straight path is shown in Figure 13.
a. Identify the time intervals during
which the velocity of the shuttle bus
is constant.
b. Identify the time intervals during
which the acceleration of the shuttle
bus is constant.
c. Find the value for the average veloc-
ity of the shuttle bus during each
time interval identified in b.
d. Find the acceleration of the shuttle
bus during each time interval identi-
fied in b.
e. Identify the times at which the
velocity of the shuttle bus is zero.
f. Identify the times at which the acceleration of the shuttle bus is zero.
g. Explain what the slope of the graph reveals about the acceleration in
each time interval.
