Three identical balls of mass m and radius R are placed on frictionless horizontal x-y plane. Ball A at (0, 0), Ball B at ( 
R, – 
R). Ball A is suddenly given an impulse 
. If collision between balls A and B is perfectly elastic while between B and C is head on and perfectly inelastic , then.

B
The y componant of relative velocity of ball A with respect to ball C after a long time is 
.
.
C
The x componant of relative velocity of ball A with respect to ball C after a long time is 
.

Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, c)
Before first collision :
After first collision
After second collision
So V AC = V A – V C
= 
+
