Question
A car is stopped at a traffic light. It then travels
along a straight road so that its distance from the
light is given by a (t) = bt2-ct³, where
b=2.80 m/s² and c = 0.110 m/s³.
For related problemsolving tips and strategies, you
may want to view a Video Tutor Solution of
Average and instantaneous velocities.
