A 2.10-kg block hangs without vibrating at the end of a spring (k 530 N/m) that is attached to the ceiling of an elevator car. The car is rising with an upward acceleration of g/3 when the acceleration suddenly ceases (at t = 0). (a) What is the angular frequency of oscillation of the block after the acceleration ceases? rad/s (b) By what amount is the spring stretched during the time that the elevator car is accelerating? cm

A 2.10-kg block hangs without vibrating at the end of a spring (k = 530 N/m) that is attached to the ceiling of an elevator car. The car is rising with an upward acceleration of g/3 when she acceleration
suddenly ceases (at t = 0).
(a) What is the angular frequency of oscillation of the block after the acceleration ceases?
rad/s
(b) By what amount is the spring stretched during the time that the elevator car is accelerating?
