2 cars collide at an intersection.
one car which has a mass of 1,400kg has a velocity of 45 km/h
the other car has a mass of 1,300kg and has a velocity of 39 km/h[E]
The cars has an inelastic collision. What are their velocity after the collision
Conservation of momentum: P total = P total prime
The Attempt at a Solution
I have tried on numerous occasions but have not achieved the correct answer.
The correct answer should be: "30 km/h [ 51 South of East.]
I got the correct magnitude of the velocity which is 30 km/h. Easy enough, but i didn't get the degrees required. Additional vector diagram is appreciated.
