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.
Each AC4400CW is capable of putting out a maximum of 180,000 lbs of tractive force. Since the potential acceleration of 540,000 pounds is greater than 100,000 lbs, the train begins to accelerate, and the drag drops down to 40,000 lbs once it's moving, but that would start climbing as the train gains speed.
