Some researchers are using motion sensing devices to study the
motion patterns of wild animals. The devices provide graphs of an
animal’s VELOCITY vs. time as it tracks its prey. The graph below
shows a segment of an animal’s VELOCITY.

A car starts at point A and
speeds up
at a constant rate in
the positive direction until it reaches point B in 3 seconds, where
it suddenly stops. The car
waits
at point B for 3 seconds. It
then travels at
constant speed
in the opposite direction,
reaching point A again in another 3 seconds.
Sketch a POSITION-TIME graph of the motion
during these 9 seconds.
Sketch a VELOCITY-TIME graph of the motion during these 9 seconds.
