A diver standing on a 50 feet high diving board calculates that he would be traveling at a speed of 87 miles per hour when he hits the water, with the acceleration of gravity being 32.2 feet/sec^2. Is the diver correct in his calculation? How fast in miles per hour would he be going when he hits the water (if he ever jumps)?
