2.1% Suppose the landing speed for a huge jet airplane is about 170 miles per hour. Assume the plane is to slow to a stop at a rate of 0.175g. Assume this rate is constant from the instant the plane touches down until the instant it comes to a full stop. Here g is the magnitude of freefall acceleration near earth's surface. Note: the m numerical value is always g = +9.8 (plus sign added for emphasis...g is always positive). a) Is g gravity? b) Is g the acceleration due to gravity? c) Under what circumstances does g = -9.8? 23 d) How far will the plane travel as it slows from touchdown to full stop? Answer in both meters and miles. e) How long does it take to stop? Assume this is elapsed time between touchdown and stop.
