Physics

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 1.00 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.20 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?

Please explain in great detail step by step if possible I am so lost

1. a. d1 = V*t=2m/s. * 1s.=2 m. Head start.

d2 = 2 + d1.
0.5a*t^2 = 2 + V1*t.
0.5*0.2*t^2 = 2 + 2*t.
0.1t^2 -2t - 2 = 0.
t = 21 s.

b. d = 2 + 2*21 = 44 m.
