hmmm do you use 9.8 or 10 for gravity? Idk how much a difference that makes but just a thought

anonymous · Answer

9.8

anonymous · Answer

I used 9.8 also so maybe using 10 will affected it?

anonymous · Answer

Actually, if you use 10 you get 115.2, but our teacher told us to use 9.8

anonymous · Answer

I think that was the reason.
