Answer:
The initial momentum is 0
Initial momentum = final momentum
Final momentum:
Resultant momentum for the two is.
Mass is constant and depends not on the direction.
12² + 9² = 225
The resultant velocity = √225 = 15m/s
Since the mass is equal we have.
Momentum = 15m
Let the velocity of the third one be v
The final momentum is = mv + 15m
0 = mv + 15m
-15m = mv
v = - 15
The velocity of the third one is :
15 m/s
