Physics

The spring shown in the figure is compressed 59cm 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∘ incline is 0.14 .
k= 80,000 N/m
m=100 kg
uk= .14
DeltaX= 59 cm

the hill the student is 10 m high from the bottom of the slopebefore the incline of 30∘.

Part A: What is the student's speed just after losing contact with the spring?
Answer: 17 m/s

Part B: How far up the incline does the student go????
