A collision in which two objects stick together is referred to as a perfectly inelastic collision. The total momentum of a system is always conserved in a collision (see section 8.35 of your textbook). initial Vi,m V,M = 0 final Vf,m+M 1. Write the equation for conservation of momentum for the scenario above. 2. Find the final velocity of the two masses (Vf,m+M) immediately after collision. Compare your result to Eq. 8.48 of your textbook.
