A $0\mathrm{.}60-$kg object connected to a light spring with a force constant of $22\mathrm{.}0$ N$/$m oscillates on a frictionless horizontal surface. The spring is compressed $4\mathrm{.}0$ cm and released from rest.

$($a$)$ Determine the maximum speed of the object.

Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m$/$s

$($b$)$ Determine the speed of the object when the spring is compressed $1\mathrm{.}5$ cm$.$
