Suppose a 91.75 kg hiker has ascended to a height of 1841 m above sea level in the process of climbing Mt. Washington. By what percent has the hiker's weight changed from its value at sea level as a result of climbing to this elevation? Use g=9.807 m/s2 and R=6.371×106 m . Keep four significant figures in your weight calculation to find the percent difference, and enter your answer as a positive value. weight change= %
