A $0.27\mathrm{kg}$ softball has a velocity of $13\mathrm{m}/\mathrm{s}$ at an angle of $22^{?}$ 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) $25\mathrm{m}/\mathrm{s}$, vertically downward, and (b) $25\mathrm{m}/\mathrm{s}$, horizontally back toward the pitcher?
