A boat is pulled into a dock by means of a winch 12 feet above the deck of the boat. 14 ft/sec 12 ft Not drawn to scale (a) The winch pulls in rope at a rate of 4 feet per second. Determine the speed of the boat when there is 15 feet of rope out. ft/sec X What happens to the speed of the boat as it gets closer to the dock? The speed of the boat increases as it approaches the dock. (b) Suppose the boat is moving at a constant rate of 4 feet per second. Determine the speed at which the winch pulls in rope when there is a total o 15 feet of rope out. ft/sec X What happens to the speed at which the winch pulls in rope as the boat gets closer to the dock? The speed at which the winch pulls in rope approaches 0
