To find <em>Speed </em>you divide distance by time.
Reasoning:
Displacement is the change in an object's position from the origin.
To find Acceleration you use the equation a=v^2/r
To find Velocity you divide the distance by the time it takes to travel that distance, then you add your direction to it.
<em>To find speed you use distance is over time</em>

A) 
B) 
Explanation:
As it is mention that the spool has mass M, radius R and moment of inertia I. In the first part of the question as the spool is not moving and r < R which means there is net torque = 0
so, 
and 
In the second part of the question from the given information, we can express the angular acceleration
=
( alpha = angular acceleration and a = translational acceleration)
We start to see more off the dark side (waning) or more of the light side (waxing) the more of the dark side we see, the less moon there seems to be. The more light side, the more moon.
