Thread: find the minimum initial speed....

ok this problem seemed pretty straight forward..but then i got down to the last line and got stumped..im not sure how im supposed to solve for theta..maybe my setup is wrong. i was wondering if someone can chck my work and then if its right, help me solve the problem for theta? it seems like i have too many unknowns....i dunno...


thanks in advance...

If this problem is not important enough to you to type in what you have done, then it not important enough to me to open a file (which might harbor a computer virus) from someone I do not know and then have to makes sense of their writing.
