Two soft objects are sliding without friction across a horizontal surface when they collide completely inelastically, sticking together. in a certain frame of reference mass m is moving at 30?
from theta x at speed v when it collides at x = y = 0 with the other mass 2 m, moving at the same speed at angle ? below the theta x axis. the objects fuse together and move off along the +x axis at speed v, which is (like theta) unknown.
