question. 50 maybe 32. Height of initial velocity. Six. What are you hearing? Well, I have 18 which gives me 32 teams making 32. Now I find out what might see value 60 for my the team, huh? Right. Thank you. 32 times zero plus c. So see? 16. So I have negative. 32. He six s a p. I'm thinking of your girl of negative 32 tea plus 60. Which is gonna give me negative thy peace, where you're 32.
