A spring 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 30 degree incline is 0.15.
K=80,000 N/m
Initial Height of spring 10 m

*student gets shot from a spring this is 10 M high until he reaches the bottom then begins going up a 30 degree incline*

What is the student's speed just after losing contact with the spring?

How far up the incline does the student go?
