Please Calculate to give actual numbers!!

Consider a damped harmonic oscillator. The oscillating mass, m, is 4 kg, the spring constant, k, 16 N/m, and the damping force F is proportional to the velocity (F = -m*alpha*v). If the initial amplitude is 20 cm and falls to half after 6 complete oscilltions, calculate

a. the damping cooefficient, alpha,

b. the energy "lost" during the first 6 oscilations

A simple harmonic oscillator is made up of a mass-spring system, with mass of 1.31 kg and a spring constant k = 148 N/m. At time t=1.66 s, the position and velocity of the block are x = 0.135 m and v = 3.958 m/s. What is the amplitude, xm, of the oscillations? Your answer should be in m, but enter only the numerical part in the box.

As you know, a common example of a harmonic oscillator is a mass attached to a spring. In this problem, we will consider a horizontally moving block attached to a spring. Note that, since the gravitational potential energy is not changing in this case, it can be excluded from the calculations. For such a system, the potential energy is stored in the spring and is given by U=12kx2, where k is the force constant of the spring and x is...
