Hey! Why did you collide when I was resting?Classical Mechanics Level 3
Particle A and B lie along same straight line. Mass of particle A is \(2.5\) kg and of B is \(22.5\) kg. Particle A is travelling with intial velocity u = \(375\) m/s while B is at rest. Then after sometime they both collide head on elastically. The total linear momentum of system is conserved. Then find the velocity of particle B after collision in m/s .
