Now Jolon and Terry tackle a problem. A block of mass 3.0 kg is attached to a horizontal spring that has a force constant of 3.00 times 103 N/m, and is free to slide on a frictionless surface as shown. The spring is compressed to xi = -8.5 cm by pushing on The block, and then The block is released. Find The work done by initially compressing The spring. Find The kinetic energy of The block when it reaches x = 0. Find The speed of The block at x = 0.
