A 0.28 kg softball has a velocity of 16 m/s at an angle of 34° below the horizontal just before making contact with the bat. What is the magnitude of the change in momentum of the ball while it is in contact with the bat if the ball leaves the bat with a velocity of (a) 21 m/s, vertically downward, and (b) 21 m/s, horizontally back toward the pitcher?
I already solved the value of momentum using vector formulas but i cant get the answer when i'm already solving the momentum with those conditions (a and b). pls help
