What if a solid cylinder of mass M = 2.50 kg, radius R = 2.18 cm, and length L = 2.7 cm, is rolling down from rest instead? With h = 79.60 m and x = 4.64 m, what is the center of mass velocity when the cylinder reaches the bottom?

The center of mass velocity is  

Explanation:

From the question we are told that

          The mass of the cylinder is  

            The radius  is  

             The length is  

              The height of the plane is  h  = 79.60  m

               and the distance covered is  

The center of mass velocity o the cylinder when it reaches the bottom is mathematically represented as

substituting values
