A certain lake is proposed as a landing area for large jet aircraft. The touchdown speed of 118 mi/hr upon contact with the water is to be reduced to 19 mi/hr in a distance of 1400 ft. If the deceleration is proportional to the square of the velocity of the aircraft through the water, a = -Kv², find the value of the design parameter K, which would be a measure of the size and shape of the landing gear vanes that plow through the water. Also find the time t elapsed during the specified interval. Answers: K= t = i i (10-3) ft-1 sec
