Question: Two hemispheres are held together by a cord which maintains a spring under compression (the spring is not attached to the hemispheres). The potential energy

Two hemispheres are held together by a cord which maintains a spring under compression (the spring is not attached to the hemispheres). The potential energy of the compressed spring is 120 J and the assembly has an initial velocity v0 of magnitude v0 = 8 m/s. Knowing that the cord is severed when Ã¸=300, causing the hemispheres to fly apart, determine the resulting velocity of each hemisphere.
