8. Dr. Abel is minding his own business, boogying to Justin Timberlake, when a criminal suddenly steals his iPod. The criminal runs at a constant velocity of 4 m/s away from Dr. Abel. Dr. Abel, starting from rest, can accelerate at a rate of 2.1 m/s2 for four seconds, at which time he is too out of shape and has to stop. a. Will Dr. Abel catch the criminal before he has to stop (i.e. - will he get his "Sexy Back")? b. How far does Dr. Abel have to run in order to catch the criminal?
