(3%) Problem 27: At the equator, the radius of the Earth is approximately 6370 km. A plane flies at a very low altitude at a constant speed of v = 278 m/s. Upon landing, the plane can produce an average deceleration of a = 21 m/s². (a) How long will it take the plane, in seconds, to circle the Earth at the equator? (b) What is the numeric value for the minimum landing distance, d (in meters), this plane needs to come to rest? Assume that when the plane touches the ground it is moving at the same speed as it was when it was flying. landing strip
