Explanation:
Acceleration of an object is calculated by finding the change in its velocity divided by time taken.
If 
is initial velocity, 
is final velocity and t is time taken. Then the acceleration of the object is given by :
.....(1)
So, the above equation is used to find acceleration. It is called the first equation of motion. After rearranging equation (1), the correct options are :
Answer:
in the acceleration process the quantity α and w must increase
the deceleration process the alpha quantity must constant a direction opposite to the angular velocity
Explanation:
Acceleration and angular velocity are related to linear
v = w xr
a = αx r
The bold letters indicate vectors and the cross is a vector product, therefore if
we can see that the relationship between linear and angular variables is direct
therefore in the acceleration process the quantity α and w must increase as well as their linear counterparts
in the deceleration process the alpha quantity must constant as the linear acceleration and must have a direction opposite to the angular velocity
The type of star is the north star
