1.	A particle of mass m moving with velocity v is collide with a stationary particle of mass 2 m . The speed of the system , after collision will be ……….
Answer» `v/2` 2v `v/3` 3v Solution : Here `m_(1)=m, v_(1) =v` `m_(2) =2M, v_(2) =0` Suppose after collision speed of the system = v Momentum is CONSERVED in collision of both PARTICLES . ` :. M_(1)v_(1)+m_(2)v_(2) =(m_(1)+m_(2))v` ` :. v. = (MV+2mxx0)/(m+2m)` ` :.v = (mv)/(3m)` ` :. v = v/3`
