(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An object is shot (from a cannon) at an angle of 33 degrees and landed 85 m away. Calculate the magnitude of the initial velocity (Hint:Look at the x direction and solve for Vox)

2. Relevant equations

Other questions I must answer. If you have time, help with these would be great, however I think if I can just find the initial velocity I should be fine.

-Calculate the maximum height (***Actually, help with this one would really be nice!)

-Calculate the time it took from launch to land (Easy enough)

3. The attempt at a solution

Well, I looked a a few different things around the internet and this forum, and I found one thing, maybe....

So, I found the equation s=Vo^2/g*sin(2*theta). Using this equation, solving for Vo, I got 27.586 m/s. This seems like a reasonable enough answer, however I have absolutely no idea if it is correct.

I may have approached it completely wrong, I really don't know....

Thanks for the help! This is due tomorrow, and I really don't understand it.
