1. The problem statement, all variables and given/known data The drawing shows a collision between two balls. Ball A has a mass of .030kg and is moving along the x axis with a velocity of +5.5 m/s. It makes a collision with ball B, which has a mass of .055kg and is initially at rest. The collision is not head-on. After the collision, the two balls fly apart with the angles shown in the drawing below What is the final velocity of ball A and B? ... .... | Ball A ... .... | 65° . A ---B--- ... .... | 37° ... .... | Ball B Can't get above picture to look right, going to take a picture of it and save it in the post A and B show the start position and Ball A and Ball B shows where they finish 2. Relevant equations M1V1 + M2V2 = M1V1'+ M2V2' Using inverse trig? 3. The attempt at a solution I saw basically the same problem in Khan's academy and in there he had one of the two ball's final velocity given. I have no real idea how to solve for two variables but here was my try: Momentum in X initial= 5.5 * .03 = .165 Momentum in Y initial= 0 m1v1+ m2v2= m1v1'+ m2v2' .030*5.5 + 0 = .03v1' +.055v2'
