We can apply the equation Ft = change in (mv) to the case of a baseball player striking a pitched ball. To impart the maximum change in momentum, mv, to the ball, the batter hits the ball with the greatest force he can muster and he also
1) extends the time of contact as much as possible by "following through."
2) makes the time of contact as short as possible, thereby increasing the force.
3) none of the above!
In the impulse-momentum equation applied to hitting the ball, the "v" represents
4) the velocity of the bat.
5) the velocity of the ball.
6) a vector quantity.
Answer: 1, 5
