SOLVED: The spring shown in the figure is compressed by an amountΔX and used to launcha 100 k g physics student. Thetrack is frictionless until it starts up the incline. The student'scoefficient of kinetic friction onthe 300 incline is μk .The student's speed just after losing contactwith the spring is observed to be 12 m/s. What is the initialcompression ΔX in the spring?How many nonconservative forces act in this problem?It is observed that the student goes 28.8 m up along theincline. What
