The spring shown in (Figure 1) is compressed 46 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? incline is 0.16. Part A What is the student's speed just after losing contact with the spring? Express your answer with the appropriate units.

v = ?

Part B How far up the incline does the student go? Express your answer with the appropriate units.

?s= ?
