- Homework Statement
- A body 'A' of mass 2m collides with a body 'B' of mass m initially at rest in the Laboratory frame. The two bodies are seen to fly off at angles 'a' and 'b' respectively with respect to the incident direction. Find whether the angles a and b acute or obtuse.
- Relevant Equations
- ##p_{x_{initial}} = p_{x_{final}}##
##p_{y_{initial}} = p_{y_{final}}##
From the above two equations, I get :
##2mv = 2mv_aCos(a) + mv_bCos(b)##
##0 = 2mv_aSin(a) - mv_bSin(b)##
But, I can't figure out how to prove how the angles should be. I think both the angles should be acute, but don't know how to show it.
##2mv = 2mv_aCos(a) + mv_bCos(b)##
##0 = 2mv_aSin(a) - mv_bSin(b)##
