A) 5m/s away from the wall
B) 9m/s away from the wall
C) 3m/s away from the wall
D) 6m/s away from the wall
Correct Answer: D
Solution :
Let V be the velocity of ball after collision collision is elastic \[e=1\] Relative velocity of sepration = relative velocity of approach \[\therefore \] \[V-1=4+1\]or \[V=6m/s\] (away from the wall).You need to login to perform this action.
