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

A spring is compressed 50cm and is used to launch a 100kg physics student. The track is frictionless until it starts up the incline. The student's coefficient of kinetic friction with the incline is 0.15. The incline is at a 30 degree angle. Spring constant = 80 000 N/m. Height of the hill student is sitting on is 10m. What is the student's speed just after losing contact with the spring?
