A cart of unknown mass is pushed 3.61 cm against a hoop spring (spring constant 59.00 N/m) and released, just as in the lab experiment. It is observed to roll down the track (after losing contact with the spring) at constant speed v. A second spring has spring constant 80.00 N/m. If the experiment is repeated, by what distance should this second spring be compressed in order for the cart to acquire the same final speed v? Answer in cm
