Two balls are about to collide. Ball 1 has a mass of 10kg, and is moving [down] at an unknown speed. Ball 2 is 11kg and is moving [up] at a speed of 6m/s. After they collide, ball 1 moves with a velocity of 8m/s [60° Up of right]. Ball 2 moves with an unknown velocity [55° down of left]. An image has been added to help picture the situation. What is the initial velocity of ball 1?
