Carbon dating: You may use the equation A(t) = A_0 e^{kt} for the amount of carbon-14 at year t. First find the value of the decay constant k from the half-life of carbon-14, 5730 years. In other words from 1/2 A_0 = A_0 e^{k cdot 5730} find k. Then find the age of a piece of wood containing 5% of its original carbon-14.
