A novelty clock has a $0\mathrm{.}0200$ kg mass object bouncing on a spring that has a force constant of $1\mathrm{.}05$ N$/$m$.$

$($a$)$

What is the maximum velocity of the object in m$/$s if the object bounces $3\mathrm{.}10$ cm above and below its equilibrium position? $($Enter the magnitude.$)$

m$/$s

$($b$)$

How many joules of kinetic energy does the object have at its maximum velocity?
