A 0.1 kg ball moving at a speed of 5 m/s + x direction collides with 0.3kg ball which is at rest. Assuming that collision is elastic find the final velocities of both the two balls. |

Answer» Answer: SINCE collision is elastic relative VELOCITY of APPROACH = relative velocity of separation n 1 =v 1 /3+U 2
u 2 =2v 1 /3 Conserving momentum m 1 v 1 =−m 1
3 v 1
+m 2 v 1 /3 0.1 3 4v 1
=m 2 2v 1 /3 m 2 =0.2 kg Explanation: |
