A novelty clock has a $0\mathrm{.}0095-$kg mass object bouncing on a spring which has a force constant of $1\mathrm{.}05$ N$/$m$.$

$$ Part $($a$)$

What is the maximum velocity of the object, in meters per second, if the object bounces $2\mathrm{.}45$ cm above and below its equilibrium position?

$$ Part $($b$)$

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