I am just reading through this free online textbook and it seems to me that there is a mistake on page 24.
http://www.anselm.edu/internet/physics/cbphysics/downloadsI/cbPhysicsIa18.pdf#page=23
He describes the muzzle velocity, which he defines as the relative velocity between two objects, as being the sum of the two objects. Which in this case is:
vM=vB+vC
This is not the relative velocity, this would be the relative velocity between these two objects:
vM=vB-vC
Am I missing something really simple or is this actually a mistake?
