Two balls are about to collide. Ball 1 has a mass of 14kg, and is moving [down] at an unknown speed. Ball 2 is 9kg and is moving [up] at a speed of 12m/s. After they collide, ball 1 moves with a velocity of 10m/s [80° Up of right]. Ball 2 moves with an unknown velocity [60° down of left]. An image has been added to help picture the situation. What is the initial velocity of ball 1?

A railroad cart with a mass of m₁ = 12.6 t is at rest at the top of an h = 10.3 m high hump yard hill. m m₂ h After it is pushed very slowly over the edge, it starts to roll down. At the bottom it hits another cart originally at rest with a mass of m₂ = 18.6 t. The bumper mechanism locks the two carts together. What is the final common speed of the two carts? (Neglect losses due to rolling friction of the carts. The letter t stands for metric ton in the SI system.)
