A 5.00-kg block is moving at 5.00 m/s along a horizontal frictionless surface toward an ideal massless spring that is attached to a wall. After the block collides with the spring, it keeps moving rightwards until the spring reaches its maximum compression of 1.68 m. After reaching maximum compression, the block and spring come to rest momentarily, and then move leftwards. While it is moving to the left, what is the speed of the block when it has moved so that the spring is compressed to only one-half of the maximum distance?
