A car is traveling in a uniform circular motion on a section of road whose radius is r.   The road is slippery, and the car is just on the verge of sliding.  If the car's speed were doubled, what would have to be the smallest radius so that the car doesn't slide and what would be your answer to this if the care were replaced by one that weighed twice as much.  Express answers in terms of r.
