1) A damped vibration is given by: x(t) = 2e^(-7t) cos(10\pit)
a) Find the values of \omega, \gamma, \omega0, and Q.
b) Find the time and the value of the first positive maximum of x after t = 0.
c) Determine the time it takes for the mechanical energy of this oscillator to fall to 1/10 of its initial value (E = E0e^(-\gammat))
