I posted this yesterday, but somehow it's like the forums have changed over night so I posted them again.

Here is a question I am a bit stuck on, my biggest problem is that I'm getting mixed up in the beginning, everything I try to do doesn't work for me. Here is the question:

A new circus act is calle the Texas Tumblers. Mary Belle swings from a trapeze, projects herself at an angle of 53 degrees, and is supposed to be caught by Joe Bob whose hands are 6.1m above and 8.2 horizontally from her launch point. You can ignore air resistance.

(a) What initial speed Vo, must Mary Belle have just to reach Joe Bob?

(b) For the initial speed calclulated in part a, what are the magnitudes and direction of her velocity when Mary reaches Joe?

(c) This isa graph questions that I can figure out on my own once I figure the rest out.

(d) The night of their debut performance, Joe misses her completely as she flies past. How far horizontally does she travel, from her initial launch point, before landing in the safely net 8.6m below her starting point?

(a) For A I first thought about using pythagoreans theorum but then I realized I had better use the angle they gave us. The only problem with that is that no matter what I do nothing seems to work out. I was thinking of using a scalar dot product but that doesn't seem to work out for my purposes, and no matter what equation I try to use I end up with a missing variable such as time, so I can't solve for Vo. Any help on this would be great as I am so lost at this point.
