I did some of the exercise, but I don't know how to apply the momentum :'(

Hello!! My name is Vale. I study civil engineering in Peru, my hometown. Sincerely, I feel a bit weird because it is the first time I participated in a website. I don't speak English so well, but I'm trying to understand more. So, I hope to keep a good vibe with everyone. Thank you! :)
