A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 2.0 m/s, skates by with the puck. After 2.00 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.10 m/s2, determine each of the following.

Question

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 2.0 m/s, skates by with the puck. After 2.00 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.10 m/s2, determine each of the following.
(a) 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 that time?

I am confused on how to get 2 relating equations to find the time.

The go the same distance. distance1=2(t) distance2=1/2 *.1(t-2)^2 set them equal, solve fodr time t. This is the time after initial passing. solve for distance.

I solved for time, did the quadratic & got 43.9 seconds. I used that to get a distance of 96.4 meters. The program said that they are both incorrect (might be due to significant figures) so I'm not sure where I went wrong.
