This problem probably isn't as hard as it looks but I'm not sure where to begin. I'm thinking of using FdeltaT = MdeltaV, but I guess I'm getting tripped up on how the angles affect this problem.

Do you recall something called the "impulse - momentum" theorem?
$\displaystyle \vec{J} = \vec{F_{ave}} \Delta t = \Delta \vec{p}$
So find the change in momentum of the ball and divide it by the time over which the impact occurred. That will be your average force.
Meh, got it. Just used the equation like I said, but I had to find the component vectors to find change in velocity. Really an easy problem if I didn't panic about seeing angles involved with everything.

This is a rough change in momentum to calculate if you haven't done it before. (pats vesperka on the back.)
