Two gliders with masses m1 = 0.200 kg and m2 = 0.300 kg are held stationary on an air-track with compressed spring in between. The gliders are then

released and the spring pushes them apart. If m1 moves at 3.00 m/s right after it is released, �nd the initial compression of the spring, if its spring constant is 300 N/m. Ignore the eff�ects of friction and air resistance.
