i got the other homework problems but i don't think I'm even close for this one. the answer that i have so far for vfinal i have sqrt( (v*cos(phi))^2 + (2v - vsin(phi)^2) but that doesn't work or feel right either. and i can't even begin to find theta

can anyone help me with the above problem? I've been trying to work it out but i can't find the answer to vfinal... or theta
