Problem
A car moves around a level circular path of radius r0 with speed v0, experiencing a centripetal acceleration a0. The driver then increases the speed to 1.40v0 while simultaneously moving to a wider lane whose radius is 1.20r0.
(a) Determine the car’s new centripetal acceleration in terms of a0. Show clear algebraic reasoning.
(b) Express the percentage change in centripetal acceleration relative to the original value a0. Indicate whether it is an increase or a decrease, and justify your conclusion.
