**A 0.14 kg baseball moves horizontally with a speed of 29 m/s toward a bat. After striking the bat the ball moves vertically upward with 46% of its initial speed. Find the direction and magnitude of the impulse delivered to the ball by the bat.**

Find the ° (measured from the initial direction of the ball)

Find the kg·m/s

Find the ° (measured from the initial direction of the ball)

Find the kg·m/s

**J = ΔP, Pf=Pi, P=mv**

**I have the initial momentum as 4.06 kgm/s, and that is just the momentum of the baseball. Or would I put initial momentum as 0? I think it would be the 4.06 because at the beginning of the problem the baseball is moving. The momentum of the baseball after the hit is 1.86 kgm/s, which I got by multiplying the 46% by the mass of the baseball, giving me 13.34 m/s and then multiplying that by .14kg giving me 1.86 kgm/s. I'm unsure how to proceed from here.**
