What is the phase constant for the harmonic oscillator with the velocity function $v (t)$ given in Figure if the position function $x (t)$ has the form $x = x_{m} \cos (蝇迟 + 蠒)$ ? The vertical axis scale is set by $v_{s} = 4.0 cm / s$ .

Short Answer

Expert verified

The phase constant for the harmonic oscillator with the velocity function $v (t)$ , if the position function has the form $x (t) = x_{m} \cos (蝇迟 + 蠒)$ , is $- 0.927 rad$ .

Step by step solution

Stating the given data

Vertical axis scale is set by $v_{s} = 4.0 cm / s$ .

Understanding the concept of displacement equation

Using the formula of velocity, we can find the phase constant for the harmonic oscillator from theposition function of form, $x (t) = x_{m} \cos (蝇迟 + 蠒)$ .

Formulae:

The velocity of a body in motion

$v = \frac{d x}{d t}$ (i)

Equation of displacement of the motion

$x (t) = x_{m} \cos (蝇迟 + 蠒)$ (ii)

Calculation of phase constant of the harmonic oscillator

Differentiating equation (ii), we get

$v = - v_{m} \sin (蝇迟 + 蠒)$ (iii)

Using the values $t = 0 s, v_{m} = 5 cm / s, v = 4 cm / s$ in equation (iii), we get

$\begin{array}{rcl} 4 cm / s & = & - 5 cm / s \sin (蝇 (0) + 蠒) \\ 蠒 & = & \sin^{- 1} (\frac{4}{5}) \\ = & - 0.927 rad \end{array}$

Therefore, the phase constant for the harmonic oscillator with the velocity function $v (t)$ , if the position function has the form $x (t) = x_{m} \cos (蝇迟 + 蠒)$ , is $- 0.927 rad$ .
