Please help! i know how to do a elastic collisions in 1 dimension, but the 2D is too confusing...here is my problem:
You have a blue ball with a mass of 1.5 kg moving with a speed of 4.5 m/s in a direction below the positive xaxis. You have a red ball with a mass of 3.6 kg moving with a speed of 2.7 m/s in a direction to the left of the negative yaxis. When the balls collide, find the final velocity (magnitude and direction) for each of the two balls.
