Interesting point! A classmate and I were just trying to figure out how to calculate sin^2 or cos^2 on our calculators--couldn't figure out what to do, nor could our TA.

Ok, thanks for the help anyway. :)

"hmm … I honestly don't know what you do now … the question doesn't seem to make sense as it is … you've been given too much information, and it's contradictory. " Yes, I agree thank you! There appears to be too much information. a_x=0, y=0, and t=1.14s after plugging in the numbers...

Ok, so we have: x=V_ox*t + 1/2 a_x t^2 16.8=14.18* t + 1/2 (0) t^2 16.8/14.18=t t=1.14 However, a need the answer for y to continue, is that correct? Do I solve for y distance with tan of y/x, since I know the angle?
