The answer is 8 meters per second 8m/s because 200 divided by 25 is 8
Answer:



Explanation:
From the question we are told that
Voltage 
Generally in a case of Y_connection
is mathematical represented as

Generally voltage drop across phase A


Generally voltage drop across phase B


Generally voltage drop across phase C


To solve this problem we will use the concepts related to angular motion equations. Therefore we will have that the angular acceleration will be equivalent to the change in the angular velocity per unit of time.
Later we will use the relationship between linear velocity, radius and angular velocity to find said angular velocity and use it in the mathematical expression of angular acceleration.
The average angular acceleration

Here
= Angular acceleration
Initial and final angular velocity
There is not initial angular velocity,then

We know that the relation between the tangential velocity with the angular velocity is given by,

Here,
r = Radius
= Angular velocity,
Rearranging to find the angular velocity

Remember that the radius is half te diameter.
Now replacing this expression at the first equation we have,


Therefore teh average angular acceleration of each wheel is
