A small mass object is attached to a horizontal spring, oscillating at a frequencyof 4 Hz. At the time instant t = 0 s, the object is at a maximum distance fromequilibrium position xmaxv(x) = 0 m/s.= +4 cm where it has the instantaneous velocity It is required to determine: a) The period and the angular frequency; b) The amplitude of the motion. c) The maximum speed and acceleration d) The position at t = 2 s.
