Mass of bat is $\"\"$ kg.

Uniform rod length is $\"\"$ .

Bat swings with an accelertion of 2.6 rev/s in a time of 0.20 s.

Find the torque.

Torque $\"\"$ , where I is the moment of inertia and $\"\"$ is the acceleration.

Angular velocity is $\"\"$ rad/s.

Angular acceleration is $\"\"$ rad/s².

$\"\"$

$\"\"$ .

Moment of inertia of rod of length $\"\"$ is $\"\"$ . \ \ $\"\"$

$\"\"$ . \ \

Substitute $\"\"$ and $\"\"$ in $\"\"$ .

$\"\"$

Torque required to produce the acceleration $\"\"$ N-m.
