A simple harmonic oscillator consists of a 100 g mass attached to a spring whose force constant is 104 dyne / cm. The mass is displaced 3 cm and released from rest. Allow motion to take place in a resisting medium. After oscillating for 10 s, the max amplitude decreases to half the initial value. Calculate
a- the damping parameter β
b- the frequency v1
c- the decrement of motion
