A spring is placed horizontally on a frictionless table. The spring constant of the spring is 50 N/m, and it is compressed 0.100 m by a 2.00 kg block. [a.] How much energy is stored in the spring?[b.] When the spring expands back to its resting position, it pushes the block away. What is the kinetic energy of the block as a result of this force?[c]. What is the velocity of the block as it is pushed away by the spring? *
