Aspring (k = 600 n/m) is at the bottom of a frictionless plane that makes an angle of 30° with the horizontal. the upper end of the spring is depressed 0.10 m, and a 2.0-kg block is placed against the depressed spring. the system is then released from rest. what is the kinetic energy of the block at the instant it has traveled 0.10 m and the spring has returned to its uncompressed length?
