animals on earth ---- 35 miles long and 18 miles wide ----. Most of you are right about most of your ideas, however, I think that most of your positions depend on "the size of the earth in relation to gravity. For example, it was pointed out that an animal that big could not move fast enough to avoid attacks. Why? Because of gravity which is related to the size of the earth. I think MAN is sized "just right" to take advantage of the size of the earth and the gravity it produces. What do you think?

The upper end of a straight ladder is leaning against the vertical side of a building, with its lower end on a horizontal sidewalk. To the consternation of the painter standing on it, the upper end is slipping down the wall at a constant rate of 2 feet/sec. The lower end is, therefore, sliding along the sidewalk. Having had a course in the Calculus, the painter is, of course, interested in how fast the lower end is moving. If the ladder is 29 feet long, how fast is the lower end moving when the upper end is 20 feet above the ground?

possible solutions...

a. 8/3 feet/sec.
b. 3/2 feet/sec
c. 48/7 feet/sec.
d. 7/12 feet/sec.
e. 15/4 feet/sec.
f. 16/15 feet/sec.
g. none of these
