Questions
A particle of mass m moving eastward with a speed v collides with another particle of the same mass moving northward with the same speed v. The two particles coalesce on collision. The new particle of mass 2m will move in the north-easterly direction with a velocity
detailed solution
Correct option is C
Initial momentum of the system P→i=mvi^+mvj^ |P→i| = 2mvFinal momentum of the system = 2mVBy the law of conservation of momentum 2mv=2mV⇒V=v2Similar Questions
Two bodies having same mass 40 kg are moving in opposite directions, one with a velocity of 10 m/s and the other with 7 m/s If they collide and move as one body, the velocity of the combination is (m/s)
