Hey guys, i cant figure this one out.(adsbygoogle = window.adsbygoogle || []).push({});

a mass attached to a spring oscillates with an amplitude of 18cm; the spring constant is k=18N/m. when the position is half the maximum value, the mass moves with velocity v=27cm/s.

a) determine the period of motion.

b)find the value of mass

i tried to find the mass first but that didnt work. i used kinematics, T= 2∏/ω, ω=sqrt(m/k) and T= 2∏sqrt(m/k) but none of them were working.

thanks for the help!
