Unformatted text preview: Examples (Uninhibited Decay): 3. Radioactive strontium-90 decays according to A ( t ) = A e " .0244 t . In 1960, radioactive stontium-90 was released into the atmosphere during testing of nuclear weapons, and was absorbed into peoples bones. How many years does it take until only 10% of the original amount absorbed remains? 4. The voltage of a certain conductor decreases over time according to the law of uninhibited decay: V ( t ) = V e kt , k < 0 . If the initial voltage is 200 volts and 3 seconds later it is 75 volts, then what is the voltage after 5 seconds?...
