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

c and d

Hey again!
Ok..
Now... The melting Point of this solid is 90°C.
Meaning That as soon as it gets to this temp... It STARTS Melting.
So at that temp... It still has some solid parts in it.
You can say its a Solid Liquid Mixture.
Additional Heat being applied at that point is not raising the temperature;rather its used in breaking the bonds in the solid. This is the Fusion stage.
After Fusion...It'd then Be a Pure Liquid with no solids in it.
So
Q'=MC∆0----- This is the heat needed to take the solid's temp from 30°c - 90°c
Q"=ml ----- This is the heat used in breaking the bonds holding the solids in the solid-liquid phase.
So
Q= Q' + Q"
Q= mc∆0 + ml
∆0 = 90°c - 30°c = 60°c
Q= 2.5(390)(60) + (2.5)(4000)
Q=6.9 x 10⁴Joules
A or possibly C because the other options have nothing to do with the size of the vibration. If i was you I would answer with A
