1. A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 15 m/s, skates by with the puck. After 3.5 s, the first player makes up his mind to chase his opponent.
(a) If he accelerates uniformly at 4.0 m/s^2, how long does it take him to catch his opponent? (Assume the player with the puck remains in motion at constant speed.)
(b) How far has he traveled in this time? I've tried to solve it by coming up with an equation for the position of each player, and set them equal to each other. Equation for the player who is chasing: X = v*t
I'm not sure what formula to manipulate in order to come up with an equation for the position of the player being chased.
Thanks in advance.
