Solution: A wooden spear was recently found in what is thought to be a Bronze Age site. Archeologists wish to carbon date the spear to verify that it's from the correct time period. We know that the half-life 14C is 5700 years and that initially living samples contain 32 grams of  14C if the current sample contains 8 grams of 14C, how old is the spear? a) 14,300 years b) 11,400 years c) 6120 years d) 2350 years e) 4860 years
