The volume of the object must be no larger than .
Explanation:
In order for an object to be able to float in water, its density must be equal or smaller than the water density.
The density of water is:
This means that the density of the object must be no larger than this value.
We also know that the density of an object is given by
where
m is the mass of the object
V is its volume
For the object in this problem, the mass is
Therefore, we can re-arrange the equation to find its volume:
So, the volume of the object must be no larger than .

Answer:
The average angular acceleration is
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
