A 1.0 kg block is sliding up a frictionless ramp towards a spring (k = 100 N/m) that is solidly attached at the top. The ramp is inclined at angle θ = 50°. Initially the block is located at position A that is distance d = 0.60 m from the end of the relaxed spring, with an initial kinetic energy of 20 J.
