Two objects of masses m1-0.44 kg and m2 0.86 kg are placed on a horizontal frictionless surface and a compressed spring of force constant k . 300 N/m is placed between them as in figure (a). Neglect the mass of the spring. The spring is not attached to either object and is compressed a distance of 9.6 cm. If the objects are released from rest, find the final velocity of each object as shown in figure (b). (Let the positive...
