Correct.

Yes, because we gave you the answer. Could you do it on a test? Could you do it if the keys were thrown at a 32 degree angle? Could you do it if you were throwing the keys up to a cliff 64 m high?

I'm not trying to attack you, I just don't like how people on here are so ready to just give up the answer, instead of trying to help you learn to do it yourself.

Yeah, Aimster!

Someday in real life you are going to accidentally throw your car keys horizontally at 8.0 m/s from a cliff 64m high and you won't have the faintest idea where to look for them and you'll probably starve in the desert.
