If a baseball leaves the bat at an angle of 45degrees 1m above the ground and clears a wall 3m high 150m away from home plate, what initial velocity would the ball have had if air resistance is negligible

We need to know how high the baseball is when it clears the wall.
I haven't checked GeoC's answer/work, but I'm assuming it's for when the baseball just clears the wall, thus it is a lower bound for initial velocity.
That's right.. I assumed y=3' at the wall.... I worked through the problem very quickly, so wouldn't be surprised if I've made an error... (although the units on the formula derived for V are correct).
Yes, I have a typo.... should have wrote rather than . However, I did not make this error when I actually worked the problem on paper. My expression for v, i.e.
