A 2kg block hangs without vibrating at t...

A `2kg` block hangs without vibrating at the bottom end of a spring with a force constant of `400 N//m`. The top end of the spring is attached to the ceiling of an elevator car. The car is rising with an upward acceleration of `5 m//s^(2)` when the acceleration suddenly ceases at time `t = 0` and the car moves upward with constant speed `(g = 10 m//s^(2))`
What is the angular frequencyof the block after the acceleration ceases ?

A

`10sqrt(2) rad//s`

B

`20 rad//s`

C

`20sqrt(2) rad//s`

D

`32 rad//s`
