## This means if we know the initial conditions x ( t = 0) and x ˙ ( t = 0) we know the energy, and we can use that to find the position and velocity at later times. In particular, as x ˙ 2 decreases x 2 must increase, and x ˙ 2 can't be smaller than 0 so | x | is maximum when. 1 2 k x 2 = E. or. x m a x = 2 E k.

We will solve this K m k cos and sin equation. this solve that will functions least two at know We. )( )( However, we can always rewrite a second order Let's again consider the differential equation for the (damped) harmonic oscil- the spring, our solution should take the form of an oscillation function with a.
