Q. A Sphere on a Horizontal Surface starts from Rest. If the Force is applied facing to the Right at the Top furthest Point of the Sphere from the Horizontal Surface, the Sphere will start experiencing Roll and Slip at the same time. In which direction will it Slide and in which Orientation (Clockwise or Counter clockwise from the Point in Contact with the Horizontal Surface) will it Rotate? What does slip and Roll Simultaneous mean? Does it mean that the Sphere or Cylinder would Slide and Rotate at separate Points in Time, or does it mean that it will Slide and Roll at the same time? What is direction of the Frictional Force?
