You are working on a model track for an exhibition. In the exhibition, a model car (mass 3.5 kg) will be pushed against a spring to get it started along a track inclined at 12. The spring is at the bottom of the track and has a spring constant of 500 N/m. The distance from where the car is released to the top of the inclined portion of the track is 5.0 m. (A) (7 pts) If we ignore friction, what is the minimum compression in the spring necessary to get the car all the way to the top of the track? (B) (9 pts) Suppose that instead, there is a small force of kinetic friction acting on the car of 4.0 N. If the spring is initially compressed 30 cm, how far up the track will the car go? For both parts (A) and (B), you may draw an energy bar chart in your solution
