Two balls are about to collide. Ball 1 has a mass of 5kg, and is moving [down] at an unknown speed. Ball 2 is 4kg and is moving [up] at a speed of 4m/s. After they collide, ball 1 moves with a velocity of 2m/s [45° Up of right]. Ball 2 moves with an unknown velocity [45° down of left]. An image has been added to help picture the situation. What is the initial velocity of ball 1?
