The figure below shows the kinetic energy of a SHM oscillator.  If Ks on the graph is 4 J, determine the spring constant of the oscillator.  Units should be N/m.

What is the phase constant (from 0 to 2π rad) for the harmonic oscillator with the velocity function v(t) given in the figure if the position function x(t) has the form x = xmcos(wt + p)? The vertical axis scale is set by vs = 5.00cm/s. Number 1.57 v (cm/s) -15 Units rad

A spring is attached to the ceiling and pulled 12 cm down from equilibrium and released. The amplitude decreases by 10% each second. The spring oscillates 18 times each second. Find an equation for the distance, D the end of the spring is below equilibrium in terms of seconds, t.

The figure to the right shows the position vs. time graph of a Simple Harmonic Motion (SHM). Write the equations of motion for this Simple Harmonic Oscillator (SHO) as a function of time, with the appropriate numbers and trig functions. Calculate the exact position, velocity, and acceleration at a time of t = 9.35 s.
