A $145$ gram baseball is in contact with a bat for $2\mathrm{.}00$ m$/$s$.$ During that time, the ball changes its velocity from $45\mathrm{.}0$ m$/$s in the horizontal to $55\mathrm{.}0$ m$/$s going straight upward. As a vector. how big a force, on average, does the bat exert on the ball during the hit?
