2m/s because the hockey puck is traveling at a constant speed ( acceleration is 0 ). Unless something acts on the hockey puck it will travel 2 m/s forever.
Answer:
B) 18,000 feet MSL
Explanation:
There are three-dimensional parts in the navigation airspace in the world. The class E airspace is mostly used in the regions with coastal areas that are relatively populated. If we consider certain forms of exceptions, the class E airspace can move in the upward direction to few feet (i.e. 1200 ft). However, this doesn't include 18,000 feet MSL.
Options a to c can be the reasons for scientific models.
But to primarily answer scientific questions,that would require an empirical and experimental approach and not use of models.
Though after getting the answers, models can be built to further explain the answers.

Answer:
c) may also be conserved
Explanation:
Momentum is conserved in both elastic and inelastic type of collisions.
But the differences is that:
In an ELASTIC type of collisions, KINETIC ENERGY IS ALSO CONSERVED.
whereas, In an INELASTIC type of collision, KINETIC ENERGY IS NOT CONSERVED.
So unless until type of collision is specified, we can not say anything about the conservation of kinetic energy after collision.
Hence, may also be conserved is the appropriate option here.
