0.50\,\text{kg}

block attached to a horizontal spring (

k = 200\,\text{N\,m}^{-1}

) is pulled

5.0\,\text{cm}

to the right of equilibrium and released from rest at

t = 0

. Taking the displacement law as

x(t)=A\cos(\omega t + \phi)

, determine: (i) the amplitude

A

, (ii) the initial phase constant

\phi

(in rad).
