2 Imagine the elastic collusion of a particle with mass 'm' having a velocity vector V_m and energy E_mmcm)* with a particle of mass M (initially being at rest). After the collision, the particle m has a velocity vector of Vi_m, which is perpendicular to vector V_m. By using momentum and conservation laws, find the energy, E_tr, transferred to the particle M during collision. Express your answer in terms of E_m
