One end of a massless, 30-cm-long spring with spring constant 25 N/m is attached to a 250 g stationary air-track glider; the other end is attached to the track. A 600 g glider hits and sticks to the 250 g glider, compressing the spring to a minimum length of 22 cm. Part A What was the speed of the 600 g glider just before impact? Express your answer with the appropriate units. 21 = μA Value Units
