Short Answer

A boat is pulled into a dock by a rope attached to the bow of the boat and passing through a pulley on the dock that is 1 m higher than the bow of the boat. If the rope is pulled in at a rate of 2 m/s how fast is the boat approaching the dock when it is 3 m from the dock? Round the result to the nearest hundredth if necessary.
