Physics Girl is standing on her skates on a frozen pond when Einswine, moving with a uniform velocity of 18 m/s, skates by with the hockey puck. 2.1 s after Einswine passes her, Physics Girl makes up her mind to chase Einswine and accelerates towards him with a constant acceleration. Physics Girl catches up to Einswine 10.0 s after she began to move. What was the magnitude of Physics Girl’s acceleration? (Assume Einswine remains in motion at constant velocity.)
