2 bodies of masses 'm' and '3m', moving with velocities 3v and v respectively along same direction, collide with each other. After collision they stick together and move with a velocity V in the same direction. Then:
Asked by adityaahuja099 | 12th Oct, 2017, 11:39: PM
Initial momentum of both bodies m×3v + 3m×v = 6×m×v
after collision combined mass is 4×m
By conservation of momentum, momentum after collision is 6×m×v
so velocity after collision is
