Find the acceleration of the specified object. (Recall that if a variable is changing at a constant rate, its acceleration is zero. A boat is pulled into a dock by means of a winch 15 feet above the deck of the boat. The winch pulls in the rope at a rate of 8 feet per second. Find the acceleration of the boat when there is a total of 17 feet of rope out. Round your answer to 3 decimal places and use a correct label. (6 points)

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
