The angular frequency of a spring block ...

The angular frequency of a spring block system is `omega_(0)`. This system is suspended from the ceiling of an elevator moving downwards with a constant speed `V_(0)`. Ther block is at rest relative to the elevator. Lift is suddenly stopped. Assuming the downwards as a positive direction, choose the wrong statement:

A

The amplitude of the block is `(v_(0))/(omega_(0))`

B

The initial phase of the block is `pi`.

C

The equation of motion for the block is `(v_(0))/(omega_(0))sin omega_(0)t`.

D

The maximum speed of the block is `v_(0)`.

A particle that hangs from a spring oscillates with an angular frequency of 2 rad//s . The spring particle system is suspended from the celling of an elevator car and hangs motionless (relative to the elevator car) as the car descends at a constant speed of 1.5 m//s .
