A hockey player is standing on his skates on a frozen pond
when an opposing player, moving with a uniform speed of 12
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 4.0 m/s2, (a) how long does it take him to catch his opponent,
and (b) how far has he traveled in that time? (Assume
the player with the puck remains in motion at constant speed.)
