A solid sphere is placed on a frictionless floor in a very long corridor and is given a quick push so that it begins to slide, without rotating, along the corridor. How would the angular speed of the sphere be changing if the floor were not frictionless? A.) It would remain zero because the net torque is still zero.
B.) It would remain zero because the angular momentum is conserved.
C.) It would be increasing until the slipping between the sphere and the floor stops.
D.) It would be increasing until the linear and the angular speeds become equal.
E.) It would be increasing until the translational motion stops.
