$32)$ A mass is attached to a spring of spring constant $60$ N$/$m along a horizontal, frictionless surface. The

spring is initially stretched by a force of $5\mathrm{.}0$ N on the mass and let go$.$ It takes the mass $0\mathrm{.}50$ s to go

back to its equilibrium position when it is oscillating. What is the period of oscillation? $32)\_\_\_\_\_\_$
