Use the law of conservation of momentum.
This will require you to add the momentum vectors of the colliding cars.
two cars, one with mass m1=1000kg and the other with mass m2= 4000kg crash in an intersection. Before the crash, car m1 was headed east with a speed of v1i= 25 m/s and the car m2 was headed north with a speed of v2i= 10m/s. After the crash, the cars stick together. what is the speed of the 2-car wreck after the collision and with what angle does it leave the crash point?
