13. You throw a tennis ball of radius R on the floor such that it rolls freely on a flat surface
for some time and then it hits a patch of ice where the coefficient of friction between the
ball and the ice is s = 0. When the ball hits the patch
(a) It continues to roll as before.
(b) It starts to spin
(c) It begins to skid
(d) none of the above
I think the answer is c) is it correct or do you think otherwise. please provide a short explanation with your answer.

could not some of the rotational kinetic energy get converted into transitional kinetic energy and cause sliding. isnt this effect same as a car skidding when it goes over ice.
