1. The problem statement, all variables and given/known data A gust of wind hits a flagpole and starts it oscillating. After 10 s, the amplitude of its motion has decreased to 25% of its initial value. What is the value of the time constant? 2. Relevant equations xmax(t) = Ae[tex]-t/\tau[/tex] 3. The attempt at a solution I know that the answer is 7.2s, but how do I find it? How do I manipulate the above equation?
