Aspring with constant k=40.0 n/m is at the base of a frictionless, 30.0 degree- inclined plane. a 0.50-kg block is pressed against the spring, compressing it 0.20m from its equilibrium position. the block is then released. if the block is not attached to the spring, how far up the incline will it travel before it stops?
