Question 10
The radioactice decay of Strontium can be modeled by the equation
where a is the initial amount and t is measured in years.
y = a (e -0.02411)
If there is a 3 kg mass of strontium being used as part of a navigation system
in a satellite, how many years will it take for the radioactive mass to decay to
1.2 kg?
