Problem
A uniform solid sphere of radius 0.10m is moving across a rough horizontal surface. At one instant its translational speed is 3.0m⋅s−1 while its angular speed is 10rad⋅s−1. At that instant:
• Is the sphere rolling without slipping?
• Which type of friction—static or kinetic—is acting on the sphere?
Justify both answers briefly.
