- Review the following situations and determine whether each is an elastic collision or an inelastic collision. elastic collision inelastic collision ______ A moving hockey puck strikes one at rest; the objects exchange velocity. ______ A collision between a volleyball and a basketball occurs; there is no deformation. ______ After the collision, objects are stuck together and moving together. ______ Momentum and kinetic energy are conserved. ______ Momentum is conserved; kinetic energy is not.Under what condition is the energy lost during a collision maximum? A) e=1.0 B) e = 0.0 C) e=-1.0 D) Collision is non-elastic.When 2 blocks smash into each other in a maximally inelastic collision which of the following is true: Choose ALL CORRECT answers. You may have to select more than one statement below: Mechanical Energy was NOT conserved during the collision The bigger block travels with a bigger velocity than the smaller block after the collision. momentum was conserved during the collision momentum was not conserved during the collision The maximum amount of mechanical energy that could be lost in the collision was lost. The final velocity of each block must be zero. The objects have the same final velocity. O Mechanical Energy WAS conserved during the collision
