the question says:
Compare the momentum of a 50-kg-dolphin swimming at 10.4 m/s and a 6,300-kg-elephant walking 0.11 m/s.
so what do i do? what kinda answer are they looking for? im just so confused physics is so not my forte!

so i put
the elephant has more momentum even thought its slower, becasue it has a larger mass.
is that what they are looking for?

Momentum is mass times velocity:
Elephant:
mv = (6300)(0.11) = 693kg m/s
Dolphin:
mv = (50)(10.4) = 520kg m/s
You could say the elephant has 693/520 = 1.333 one third more momentum than the dolphin.

www.dictionary.com - compare
verb (used with object) 1. to examine (two or more objects, ideas, people, etc.) in order to note similarities and differences: to compare two pieces of cloth; to compare the governments of two nations
just look up the equation for momentum. I think you will find the problems very easy to solve.
