(8a) Anita is standing on her skates on a frozen pond when her brother, Ahmed, moving with a uniform speed of 17.3 m/s, skates by with the hockey puck. After 1.844 s, Anita makes up her mind to chase Ahmed. If she accelerates uniformly at 1.3 m/s2, from the time Anita starts skating, how long does it take her to catch Ahmed? (Assume Ahmed remains in motion at constant speed.)
