🤓 Based on our data, we think this question is relevant for Professor Kadel's class at FIU.

Solution: A 1300 kg car moving on a horizontal surface has speed exttip{v}{v} = 80 km/h when it strikes a horizontal coiled spring and is brought to rest in a distance of 2.3 m. What is the spring stiffness constant of the spring?
