Two identical balls A & B having velocity of 0.5 m/s & -0.3 m/s respectively. colloid elastically in 1-0. The velocity of A & B after collision will be?
AnswerClick to flip back
A
-0.3 m/s,0.5 m/s
💡 Explanation:
In elastic collision of identical balls, velocities are exchanged. A(0.5) gives 0.3 to B, B(-0.3) gives -0.5 to A. Final: A=-0.3 m/s, B=0.5 m/s. Mass cancels out.
