Afreighter is moving at a speed of 8 knots when its engines suddenly stop. if it takes 10 minutes for the freighter's speed to reduce to 4 knots, determine its speed and distance travelled 30 minutes after the engines were stopped. the freighter's deceleration is proportional to the square of its speed, i. e., a = -k*v^2. (1 knot = 6076 ft/hr)
