1. The problem statement, all variables and given/known data A baseball strikes a bat. It's moving at 40m/s to the left horizontally. When it hits the bat it leaves at 60m/s with an angle of 30 degrees to the horizontal. The mass of the ball is 0.25kg. 2. Relevant equations P(momentum)=mv Pf-Pi=ΔP ΔP=J(impulse) 3. The attempt at a solution Since we are speaking in vector terms I would assume that 60 should be negative. But anyways the question asks to write the net impulse in vector notation. It reads it as J=Jxi + Jyj. Since change in momentum(delta P) is equal to impulse; If I was trying to find the impulse in each direction like the question asks, how could I do it? I was thinking I could do: the impulse for the x-direction should be: (0.25)(-60cos30) - (0.25)(40cos0) the impulse for the y-direction should be: (0.25)(-60sin30) - (0.25)(-60sin0) I ended up with: J=-26i -7.5j Is this correct? Thank you very much!!
