A 0.180kg block of ice is placed against a horizontal, compressed spring mounted on a horizontal tabletop that is 1.40m above the floor. The spring has force constant 2000N/m and is initially compressed 0.045 {\rm m}. The mass of the spring is negligible. The spring is released, and the block slides along the table, goes off the edge, and travels to the floor. If there is negligible friction between the block of ice and the tabletop, what is the speed of the block of ice when it reaches the floor?
