The speed of block B in terms of the distance (d) it has descended is
<h3>How to determine the speed.</h3>
In order to determine the speed of block B in terms of the distance (d) it has descended, we would apply the work-energy theorem as follows:
The work done due to gravity is given by:
The work done due to friction is given by:
The angular velocity of pulley is given by:
Applying the work-energy theorem, we have:
