A moving white hockey puck collides elastically with a stationary red hockey puck on a frictionless horizontal surface. No net external force acts on the two-puck system. Select all of the following statements that must be true for this elastic collision.
1. The kinetic energy of the white puck is conserved (same before and after the collision)
2. The linear momentum of the white puck is conserved.
3. The linear momentum of the two puck system is conserved.
  • a)
    1 and  3 only
  • b)
    1 and 2 only
  • c)
    3 only
  • d)
    1 only

The angular momentum of the two pluck will remain conservated since no extra force is involved and elastically white hockey pluck collide with stationary red hockey pluck as its a frictionless horizontal surface pluck will keep moving forward with same speed

Only C is correct. the speed of the white puck will decrease, so the momentum (P=mv) and kinetic energy (KE=.5*m*v^2) will also decrease. The red puck gains speed, so it's momentum will increase. The momentum in a closed system is conserved....
