A 0.600 kg mass oscillates at the end of a spring with stiffness of k= 300 N/m. The initial amplitude is 0.500 m. The damping force is proportional to the velocity, "-av".
A. If the amplitude decreases from 0.500 m to 0.350 m in 2.500 s, what is the damping constant "a" ?
Note: The answer in letter A should be 7.44 × 10^-2 kg/s
