A mass of $0\mathrm{.}7kg$ is attached to a horizontal spring whose stiffness is $28\frac{N}{m}.$ Friction is negligible. At $t=0s$ the spring has a stretch of 

 

$0\mathrm{.}34m$ and the mass has a speed of $1\frac{m}{s}.$

 

 a$)\mathrm{}$$$Find the initial kinetic energy of the mass. 

 

 $K_i=$

 

 b$)\mathrm{}$$$Find the initial energy stored in the spring. 

 

$U_i=$

 

 c$)\mathrm{}$$$What is the amplitude $($maximum stretch$)$ of the oscillation? 

 

$s_{\text{m}\text{a}\text{x}\text{.}}=$

 

 d$)\mathrm{}$$$ What is the maximum speed reached by the mass? 

 

$v_{\text{m}\text{a}\text{x}\text{.}}=$
