I'm lost on how to answer the a-section of this question and wasn't able to reach the b-section.
Two objects of masses mi=0.56 kg and m2*0.88 kg are placed on a horizontal frictionless surface and a compressed spring of force constant k = 280 N/m is placed between them Neglect the mass of the spring The spring is not attached to either object and is compressed a distance of 9.8 cm. If the objects are released from rest find the final velocity of cach object.
