$4.$ This question discusses a horizontal simple harmonic oscillator. The simple harmonic oscillator consists of a block of mass $2\mathrm{.}0$ kg attached to a spring of spring constant $100\frac{N}{m}.$ When $t=1\mathrm{.}0s,$ the position and velocity of the block are $x=0\mathrm{.}129m$ and $v=3\mathrm{.}415\frac{m}{s}.$

$($a$)$ What is the amplitude of the oscillations?

$[5]$

$($b$)$ What was the position of the block at $t=0s?$

$[5]$

$($c$)$ What was the velocity of the block at $t=0s?$

$[5]$

$5.$ A horizontal string fixed at both ends is $8\mathrm{.}40$ m long and has a mass of $0\mathrm{.}120$ kg $.$ It is
