Let V be the speed of a baseball bat just before the instant of initial contact with a baseball. Let v be the initial speed of the ball just before impact. Neglecting spin effects of the ball and treating both the ball and the bat as point masses (assuming the mass of the bat the mass of the ball), the maximum speed (with respect to the ground) at which a pitched ball can be "launched" by a bat is
A) $| v + V |$
B) $| \mathrm { v } - \mathrm { V } |$
C) $| 2 v + V |$
D) $| 2 V - v |$

Question

Let V be the speed of a baseball bat just before the instant of initial contact with a baseball. Let v be the initial speed of the ball just before impact. Neglecting spin effects of the ball and treating both the ball and the bat as point masses (assuming the mass of the bat > the mass of the ball), the maximum speed (with respect to the ground) at which a pitched ball can be "launched" by a bat is
A) $| v + V |$
B) $| \mathrm { v } - \mathrm { V } |$
C) $| 2 v + V |$
D) $| 2 V - v |$

The Answer of Let V be the speed of a baseball bat just before the instant of initial contact with a baseball. Let v be the initial speed of the ball just before impact. Neglecting spin effects of the ball and treating both the ball and the bat as point masses (assuming the mass of the bat > the mass of the ball), the maximum speed (with respect to the ground) at which a pitched ball can be "launched" by a bat is
A) $| v + V |$
B) $| \mathrm { v } - \mathrm { V } |$
C) $| 2 v + V |$
D) $| 2 V - v |$

Let V Be the Speed of a Baseball Bat Just ∣v+V∣| v + V |∣v+V∣

Let V Be the Speed of a Baseball Bat Just $| v + V |$
