A1.8-kg block is pushed up against a spring whose force constant is650 N/m, compressing it 5.1 cm. When the block is released it moves horizontally without friction until it launches off the edge of a table 0.53 m above the ground. Discover the horizontal distance, d, covered with the block during its fall to the ground.
