A 2.00 kg block hangs without vibrating at the end of a spring(k=500 N/m) that is attached to the ceiling of an elevator car. Thecar is rising with an upward acceleration of g/3 when theacceleration suddenly ceases (at t=0). a.) What is the angular frequency of oscillation of the block after the accelerationceases? b.) By what amount is the spring stretched during the timethat the elevator car is accelerating? This distance will be the amplitude of the ensuing oscillation of the block.
