Question

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

Answer 1

Centripetal acceleration is the acceleration of an object acted upon a force that pulls it toward the center of origin. For constant speed, there is no acceleration, since acceleration is defined as the difference of velocities at an elapsed time. Hence, if speed doubles, then the centripetal acceleration would increase as well.
