Calculate the momentum of a elephant charging

Solve the given problems:

Problem I: Calculate the momentum of a 2140 kg elephant charging a hunter at a speed of 7.49 m/s.

Problem II: What is the momentum of the 89.0 kg hunter running at 7.37 m/s after missing the elephant?

I've been having quite a bit of trouble understanding this problem, Thank You so much for your help. Thank you.
