Question

The angular frequency of a spring block system is ω0. This system is suspended from the ceiling of an elevator moving downwards with a constant speed v0. The block is at rest relative to the elevator. Lift is suddenly stopped. Assuming the downwards as a positive direction, choose the wrong statement : 

Options

A.the amplitude of the block is
B.the initial phase of the block is π
C.the equation of motion for the block is sin ω0t
D.the maximum speed of the block is v0.

Solution

Maximum speed = v0 ⇒ A =
So equation of motion x = sin (ω0t)
