An object, which has a mass of 6.0 kg. is moving to the right with a velocity of 8.0 m/s when it collides with a second mass of 12.0 kg which is initially at rest. After the collision, the 12.0 kg mass moves off to the right with a new velocity of 5.33 m/s. Neglect friction. Before Ptotal +48 kg m/s m= 6kg After V=8m/s V'=? m = 6kg V=0 m=12kg m=12kg V'=5.33 a. Write the momentum conservation equation in terms of variables (m,v). b. Determine the velocity of the 6.0 kg object after the collision c. Is the collision elastic? How do you know? Support your answer with evidence.
