The spring shown in the figure is compressed 50cm and used to launch a 100 kg physics student.The track is frictionless until it starts up the incline. Thestudent's coefficient of kinetic friction on the 
incline is 0.15.
a) What is the student's speed just after losing contact with the spring? Answer in m/s
b) How far up the incline does the student go? Answer in m

to 
, a distance of 20.0 m up the incline (and block B drops downward a distance of 20.0 m) if the system starts from rest.
