In this problem, we will be using the formula p=mv. Momentum equals mass times velocity. We need to first get km/hr into m/s as that is how velocity is measured. So, 1 kilometer is equal to 0.278 m/s. So we multiply 22 to get 6.116 m/s for Car A. Car B is 6.95 m/s. Take Car A now. p=1200 times 6.115 to get 7,338. Car B now is 1900 times 6.95 to get 13,205. Momentum stays the same. Therefore, the answer would be that the momentum before the collision is equal to the momentum after the collision.
