Alexander, who weighs 180 lb, decides to climb Mt. Krumpett, which is 5570 m high. For his food supply, he decides to take nutrition bars. The label on the bars states that each 100-g bar contains 10 g of fat, 40g of protein, and 50 g of carbohydrates.

In this problem you do not need to assume the work of climbing the mountain is 4 times the work of just lifting the weight straight up. You should calculate the number of kJ needed to lift the 171 lb mass 5640 meters and then double this number for the round trip. Remember to watch units!

Question-Alexander wants to know exactly how many bars to pack in his backpack for the journey. To provide a margin of safety, he assumes that he will need as much energy for the return trip as for the uphill climb. How many bars should Alexander pack?
