The spring shown in the figure is compressed44  cm and used to launch a 100 kg physics student. The track is frictionless until it starts up the incline. The student'scoefficient of kinetic friction on the 30? incline is 0.11.

The spring shown in the figure is compressed44 cm and used to launch a 100 kg physics student. The track is frictionless until it starts up the incline. The student'scoefficient of kinetic friction on the 30? incline is 0.11. What is the student's speed just after losing contact with the spring? How far up the incline does the student go?

Explanation / Answer

Initially, the student has 2 sources of energy.
1) The student is 10 meters above the lowest point.
Potential energy = mass * g * h = 100 * 9.8 * 10 = 9,800 J
2) The student is sitting against a compressed spring.
Potential energy =
