Question

HW 5.5. The drawing shows a top-view of a collision between two balls. Ball A has a mass of 0.03 kg and is moving along the positive c-axis at 5.5 m/s. It makes a collision with ball B, which has a mass of 0.05 kg 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. + 5.5 m/s At rest a) What are the final speeds of balls A and B? b) Find the kinetic energy of the A+B system before and after collision and determine the type of collision: elastic, (somewhat) inelastic, or completely inelastic? c) If the balls are made of clay and stick to one another after the collision, what are the speed and direction of the resulting blob of clay? What type of collision is this?
