A hockey player is standing on his skates on the Rideau Canal when an opposing player, moving with a uniform speed of 2.8 m/s, skates by with the puck. After 3.0 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 3.5 m/s^2
a. How long does it take him to catch his opponent?
b. How far has he travelled in this time? (Assume the player with the puck remains in motion at a constant speed.)
