10) A spring attached to a wall is compressed by 12.5[cm] and a block of mass 1.0[kg] is held against the compressed spring. When the block is released and the spring is allowed to extend, the block leaves the spring with a velocity of 0.25 [m/s]. What is the value of the spring constant, k, of the spring, and how hard did the spring push on the block right at the moment the block was released from rest? Assume all of the motion is taking place in a horizontal plane without friction.
