Car 1 approaches an intersection with a momentum of p1i=(11,000 kg*m/s)x + (-370 kg*m/s)y. Car 2 approaches the same intersection with momentum p2i= (4,000 kg*m/s)x + (2470 kg*m/s)y. The cars collide and immediately the momentum of Car2 is p2f= (2100 kg*m/s)y. What is the final momentum of Car 1??
The final momentum of car two is whatever it takes both cars to equal the total momentum of both cars before the collision.
p1i + p2i = p2f + p1f
Solve for pif
A 40-kg cart moving at 120 km/h collides head on with an approaching 50-kg cart, moving at 20 km/h ( in the opposite direction). if the two carts stick together what will be their speed?
