2. Model the following mass-spring system. Make sure to select your coordinates, draw the free-body diagram(s), and derive the final equations of motion. Simplify your final answer as much as possible. Fee Ki eeee K eeeee M Do not model friction, nor gravity. The system is capable of moving in the horizontal direction only. k = 8 k k2 N m = 14 N m m = 20 kg 3. For problem #2, calculate the change in potential energy of each spring. Spring #1's initial displacement was 0.59 m, and spring #2's final displacement was 0.15 m. 2. Model the following mass-spring system.
