Two cars a ; b, before they collide. b a
car b of mass 1200 kg, is stationary. car a, of mass 2000 kg, is traveling towards car b at 18m/s
the cars collide ; car b experiences an impulse. car a continues to move in the same direction, with a momentum of 21 000 kg m/s
calculate the momentum of car b immediately after the collision

Answer:
By conservation of Momentum:
* + * = * + *
= 2000 Kg
= 1200 Kg
= 18 m/sec
= 0 m/sec
* = 21000 Kg m/sec
* = ?
Putting all the values in above equation, we get:
= 12.5 m/sec.
