1. The problem statement, all variables and given/known data A body with mass of m kg (A) is sliding horizontally in a frictionless surface at the velocity,V0. In front of it are two bodies (B and C) , each with a mass of m kg attached with a spring whose force constant is k. If the collision between A and B is elastic, how to calculate the velocities of A,B and C after the collision? I took a,b and c respectively as velocities of A,B and C after the collision 2. Relevant equations Using C.O.L.M mv0=ma+mb+mc v0=a+b+c Using C.O.M.E 1/2mv02=1/2ma2+1/2mb2+1/2mc2 What should i do next?
