m [4 points] A mass m rests on a smooth table and a mass M strikes it from the left with velocity Vo. After the collision at t = 0, the two particles have velocities V; and of. (a) Write down the total momentum, before and after the collision. Write down the total energy, before and after the collision. (b) Let M = m and use the conservation theorems. Based on (a), show that Vf=0 'Uf=Vo
