A mass M = 0.435 kg moves with an initial speed v = 3.43 m/s on alevel frictionless air track. The mass is initially a distance D =0.245 m away from a spring with k = 811 N/m, which is mountedrigidly at one end of the air track. The mass compresses the springa maximum distance d, before reversing direction. After bouncingoff the spring, the mass travels with the same speed v, but in theopposite direction.
a) Determine the maximum distance that the spring iscompressed.
b) Find the total elapsed time until the mass returns to itsstarting point.
