Veriticle springs; period and mass?


Quote by wow22 View Post
Okay thanks! Well our lab asks us when it is in dynamic equilibrium :S do I should write that there is home?
i've no idea

what has your professor given you as the definition of dynamic equilibrium?

when forces are balanced, the mass will move at a constant velocity.

but there's no constant velocity here

(unless either
i] we regard the velocity at any point as instantaneously constant, or

ii] it means that the magnitude of the velocity is instantaneously at a maximum or minimum)
