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 1 m/s how fast is the boat approaching the dock when it is 7 m from the dock? Do not round any values in your calculation. Please solve and for each step explain using words how you got to this solution, and include any names of rules or formulas while you use them. I need clarity and preciseness please
