m = 2 kg is launched up the circular ramp by compressing and releasing a spring with k=5kN/m. If the ramp has ρ=1.5m: a) How far must the spring be compressed for the box to be traveling at 2 m/s when it reaches point B, neglecting friction? b) How far must the spring be compressed to reach a point 180 degrees from (i.e. directly above) point A, again neglecting friction? c) Will the box be able to reach point B if the coefficient of kinetic friction of the ramp, μk = 0.3?

Question
A box with m = 2 kg is launched up the circular ramp by compressing and releasing a spring with k=5kN/m. If the ramp has ρ=1.5m:
a) How far must the spring be compressed for the box to be traveling at 2 m/s when it reaches point B, neglecting friction?
b) How far must the spring be compressed
to reach a point 180 degrees from (i.e.
directly above) point A, again neglecting friction?
c) Will the box be able to reach point B if the coefficient of kinetic friction of the ramp, μk = 0.3?
