The spring shown is compressed 50 cm and used to launch a 100-kg physics student. The track is frictionless until it starts up the incline. The student's coefficient of kinetic friction on the 30o incline is 0.15.
a. How far up the incline does the student go?
b. The spring is replaced with a "sproing," which exerts a force described by F = k(?s)3. If this Sproing (k = 80,000 N/m3) is compressed 50 cm, what is the student's speed just as it loses contact with it?
