Dynamics question involving impulse momentum

The question is:

A 5oz baseball is 3ft above the ground when it is struck by a bat. The horizontal distance to the point where the ball strikes the ground is 180ft. Photographic studies indicate that the ball was moving approximately 100ft/s before it was struck, the duration of the impact was 0.015s, and the ball was traveling at 30 degrees above the horizontal after it was struck. What was the magnitude of the average impulsive force exerted on the ball by the bat?

So I used kinematics to find the velocity of the baseball right after impact, utilizing the distance it traveled. I found it to be 112.48ft/s, whether that's correct or not I have no idea. So using that, I used the formula (t2-t1)SUM(Fbat)=MV2-MV1. I found the answer to be 2029.3i + 1172j - 6666.7. I'm thinking I did something wrong.
