Hello need some help. Also can you show me the process.
A car is traveling in uniform circular motion on a section of a road whose radius is r. The road is slippery, and the car is just on the verge of sliding. (a) if the car's speed was doubled, what would have to be the smallest radius in order that the car does not slide? Express your answer in terms of r. (b) what would be your answer to part (a) if the car were replaced by one that weighed twice as much, the car's speed still being doubled?
