Answer 1

I would go wit a just to be sure double check

Answer 2

okay that's what i thought thank you

Answer 3

welcome

Answer 4

\(\large h = h_0 + ut - \frac{1}{2}gt^2\)

Answer 5

FATBOI2K12, why is it A?

Answer 6

my lucky guess

Answer 7

I think you're both wrong... should be C

Answer 8
