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?

Use the law of conservation of momentum.

This will require you to add the momentum vectors of the colliding cars.
