Explanation:
From the question we are told that
From the question we are told that
The length of the bat is \
The initial linear velocity is
The time is
The velocity at t is
Generally average angular acceleration is mathematically represented as
Where is the finial angular velocity which is mathematically evaluated as
and is the initial angular velocity which is zero since initial linear velocity is zero
So
