Entropy Help!

I have an assignment for my class that has to do with entropy, and I'm just curious about a few concepts with the entropy questions.
A lead bullet moving at 150m/s at 150Celcius hits a 10Celcius lake, Calculate the entropy change.
I think I can do the entropy change due to the bullet cooling down and heating the lake, for the bullet and the water.
But, would the entropy of the water change due to the bullet stopping in the water? Since the kinetic energy of the bullet would heat up the water? We havent dealt with any processes dealing with kinetic energy.
Thanks.

What's more, the bullet itself, even at the same temperature as the lake, has some entropy in it.
