Truck suspenslons often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper colil spring mounted on the axle, as shown in the figure below. When the main leaf spring is compressed by distance the helper spring engages and then helps to support any additional load. Suppose the leaf spring constant is Yo 4.75 x 105 N/m, the helper spring constant is 3.40 x 105 N/m, and y 0.500 m.

Consider a Hot Wheels™ car with a mass of 121 g, that is pushed by a student along a track so that it is moving at 5 m/s. It hits a spring (k = 92.5 N/m) at the end of the track, causing it to compress. How far did the spring compress to bring the car to a stop? Calculate the answer in cm and make sure to include the unit. Report your final answer with three significant figures.
