The drawing shows a collision between two pucks on an air hockey table. Puck A has a mass of 0.025 kg and is moving along the x axis with a velocity of 15.5 m/s. It makes a collision with puck B, which has a mass of 0.050 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the final speeds of
(a) Puck A
(b) Puck B. |
