A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00 s. What
is its acceleration in m/s
A busy chipmunk runs back and forth along a straight line of acorns
that has been set out between his burrow and a nearby tree.
At some instant the chipmunk moves with a velocity of -1.15
m/s. Then, 2.11 s later, it moves at a velocity of 1.63 m/s.
What is the chipmunk's average acceleration during the 2.11-
s time interval in m/s
