Answer to Question #11579 in Mechanics | Relativity for Zandra

Question

A solar powered car is traveling at a constant speed around a track. What happens to the centripetal acceleration of the car if the speed is doubled?

Answer 1

It increases by a factor of 4, because

Fc = mv²/r.

Also,

Fc = ma,

so we conclude that the relationship between a and v is a squared relationship.
