A spring (k 200 N/m) is fixed at the top of a frictionless plane inclined at theta = 40 degree.
a. A 1 kg block is projected up the plane, from an initial position that is distant d=0.6 m from the end of the relaxed spring with an initial kinetic energy of 16 J. What is the kinetic energy of the block at the instant it has compressed the spring 0.2 m?
