Red car has a mass m= 5.79g and blue carhas a mass m= 5.13 g. They head towards each other along the x-axis moving in

opposite directions for a head-on collision. Red carcomes in with a speed of up = 8.73m/s moving to the right. Blue car is moving tothe left heading towards red car with the same magnitude of momentum as red car. The collision is perfectly elastic.

1/ Find initial speed of red car and blue car?

2/ Find final speed of blue car?
