An mаss оn а hоrizоntаl, frictionless surface is attached to a spring, displaced 0.8 m from its equilibrium position, and then released from rest. After 1.5 seconds, its displacement reaches equilibrium the first time. Find its frequency, its period, and angular frequency. Give the answer for frequency as a whole number, round the period to the hundredths place, and the angular frequency to the tenths place. Be sure to include the units, put a space between your numerical answer and the unit. Answers: The frequency is [frequency]. The period is [period]. The angular frequency is [angular].
