in opposite directions with equal speeds Using the principle of conservation of linear momentum, we can write: Initial momenta = Final momenta \Rightarrow M $\times$ 0 = M/2 v_1 + M/2 v_2 \Rightarrow v_1 = - v_2 where M is the initial mass of the body, at rest. The final mass of the two pieces moving with equal speeds in opposite direction is equal to M/2
