Find the height to fall from a skyscraper and hit the ground at a speed of 56 km/h. (5 Points) min . Figure shows a spring-loaded nutcracker. The device consists of a 2.5 kg block A suspended on a rope with negligible mass. The string is connected to a spring with a spring coefficient k = 1000 N/m. Let x be the position of the right end of the spring. The non-stretched spring's length is 0.1 m, but at some point the righe end is streched to x = 0.25 m. In other words, the 4 cm 上 stretched length is 0.15 m. The distance between the bottom of block Aand the ground is 0.16 m, and the block falls at a speed of 4.22 m/s. Find the speed of the block when its height from the ground is 4 cm (i.e., the height of walnet). (15 Points) Tx4 h A
