r=miles 1mile is 5280
w=pounds pounds is 100
100 pounds at sea level. find value of c that makes the equation true.( sea level is 3963 miles from the center of the earth.) use the value of c to find weigh in death valley (282 ft. below sea level.) use the value of c to find weigh in mount mckinsey (20320 ft above sea level.)
hint: the formula is W=Cr^-2
