A novelty clock has a $0\mathrm{.}017-$kg mass object bouncing on a spring which has a force constant of $1\mathrm{.}2$ N$/$m$.$

$-$ Part $($a$)$

What is the maximum velocity of the object, in meters per second, if the object bounces $2\mathrm{.}6$ cm above and below its equilibrium position?

vmax $=$

$$ Part $($b$)$

How much kinetic energy, in joules, does the object have at its maximum velocity?
