  1. initial velocity of the partical is v0
    2. 	
  2. final velocity of the partical is v1
    3. 	
  3. let velocity of the wedge be V
    4. 	
  4. alpha=a
    	
  • apply linear momentum of conservation in direction parllel to the inclined surface
    • 	
  • mv0cosa=mv1sina+MVcosa
    • 	
  • =since (M=2m)
    • 	
  • v0cosa=v1sina+2Vcosa
    • 	
  • v1=(v0-2V)cota              (eq=1)
apply linear conservation of momentum direction perpendicular to inclined suface
    	
  • mv0sina=MVsina-mv1cosa
    • 	
  • v0sina=2Vsina-v1cosa
    • 	
  • v1=(2V-v0)tana             (eq=2)
from eq 1 and 2
    	
  • v0=2V
    • 	
  • and therefore  v1=0 from eq 2
it means the partical doesn’t go upward after collision 
hence two impacts occur at the same time
so the time taken between them is 0 sec
