Wnon-conservative forces = ΔEnergy
The Attempt at a Solution
I understand that I am to solve for the D in Wnon-conservative forces since I know the friction force. I am just having trouble understanding what the initial/final kinetic rotational/translational energy of the system. It is saying derive an expression of distance BEFORE it begins rolling forward without slipping, I know that if a sphere is rolling forward without slipping, it has both kinetic translational and rotational energy, so if it's saying before this happens, are they saying that the initial conditions only include translational kinetic energy?
