(Note: Please be careful with roundoff error in this problem.) The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 2.7 kg and is moving along the x axis with a velocity of +5.5 m/s. It makes a collision with puck B, which has a mass of 6.7 kg and is initially at rest. After the collision, the two pucks fly apart with the angles shown in the drawing. 65 +5.5 m/s 37 At rest Before collision After collision (a) Find the final speed of: puck A: 2.077 * m/s x m/s puck B: 3.123 (b) Find the kinetic energy of the A+B system: before the collision: 40.83 after the collision: 38.45 x J What type of collision is this? somewhat inelastic
