The New Haven Green, a square reserved for the public, is now a pedestrian area surrounded by stately trees, the Yale campus, and an assortment of museums and architecturally significant homes and churches. The downtown is generally clean and attractive and is known for its large number of trees.
A 0.500-kg glider, attached to the end of an ideal spring with force constant k = 450 N/m, undergoes SHM with an amplitude of 0.040 m. Compute (a) The maximum speed of the glider; (b) The speed of the glider when it is at x = -0.015 m; (c) The magnitude of the maximum acceleration of the glider; (d) The acceleration of the glider at x = -0.015 m; (e) The total mechanical energy of the glider at any point in its motion.
Guinness World Records recognized NASA's X-43A scramjet with a new world speed record for a jet-powered aircraft - Mach 9.6, or nearly 7,000 mph. The X-43A set the new mark and broke its own world record on its third and final flight on Nov. 16, 2004. In March 2004, the X-43A set the previous record of Mach 6.8 (nearly 5,000 mph). The fastest air-breathing, manned vehicle, the U.S. Air Force SR-71, achieved slightly more than Mach 3.2. The X-43A more than doubled, then tripled, the top speed of the jet-powered SR-71.
