.

for a damped harmonic oscillation , the equation of motion is md^2x/dt^2+(gamma)dx/dt+kx=o with m=0.025kg,(gamma)=0.07kg/s and k=85N/m.

*calculate the period of motion

*number of oscillation in which its amplitude will become half of its initial value

*the number of oscillation in which its mechanical energy will drop to half of its intial value

*its relaxation time

*quality factor
