Problem

A car experiences a centripetal acceleration of 5.0 m/s2^2 as it rounds a level circular track at 20 m/s. If the car’s speed is increased to 30 m/s while the track radius remains unchanged, determine (i) the new centripetal acceleration and (ii) the percentage change relative to the original value.
