An object’s weight depends
on its height above the surface of the earth. If a man weighs 190 pounds on the
surface of the earth, then the man's weight in pounds (W) x miles above the
surface is approximated by the formula:
W = (190⋅4,000^2) / (4,000+x)^2
For each problem below, approximate the weight
of a 190-pound person at the given height above the surface of the earth.
Remember, 1 mile = 5,280 feet.
1. 100 miles
2. 1,000 miles
3. 1,056,000 feet
4. 10,000,000 feet
