1. The oscillation of a mass on a frictionless surface, shown in the figure below, is characterised by the following parameters Amplitude = 6.0 cm Maxımum specd = 31.0 cm/s Position at t = 0 is x(0) = +20 cm Imitial velocity is to the left (1 e v̟(0) < 0) Mass is m = 03 kg www (a) What is the force constant of the spring? (b) What is the angular frequency w of this motion? (c) What is the period 7'of this motion (d) If the position of the mass is x(t) = A cos(wot + w), what is the phase constant, @? Be sure that your answer gives the correct sign for v,(0) (e) Wrste down expressions for x(t) and v(t)
