11) A boat is pulled into a dock by a rope attached to the bow of a boat and passing through a pulley on the dock that is 1 meter higher than the bow of the boat. If the rope is pulled in at a rate of 0.5 m/s, how fast is the boat approaching the dock when it is 12 meters from the dock? bow of boat rope y 0 1 m pulley dock shore
