A 13.8 kg block and a 25.5 kg block are resting on a horizontal frictionless surface. between the two is squeezed a spring (spri
ng constant = 1131 n/m). the spring is compressed by 0.164 m from its unstrained length and is not attached permanently to either block. with what speed does each block move away when the mechanism keeping the spring squeezed is released and the spring falls away?
