Answer:
Explanation:
From the question we are told that
The mass of the bat is
The bat length is
The distance of the bat's center of mass to the handle end is
The moment of inertia of the bat is
The objective of the solution is to find x which is the distance from the handle of the bat to the point where the baseball hit the bat
Generally the velocity change at the end of the bat is mathematically represented as
Where is the velocity change at the center of the bat which is mathematically represented as
We are told that the impulse is J so
And is the change in angular velocity which is mathematically represented as
Now we have that
Before a swing when the bat is at rest the velocity change a the end of the bat handle is zero and the impulse will be 1
So
=>
substituting values
