An archeologist unearths a skeleton of a mastodon. Analysis shows the skeleton to a carbon-14 activity of 2 cmp (counts per minute per gram). If we know the skeleton had an initial carbon-14 activity of 16 cpm when the mastodon died and that the half-life of caron-14 is 5730 years. How long ago did the mastodon die?
