Imparting or conveying false information
Dropping the sandbag depletes the energy stored in the cart-spring system. As a result, the amplitude cannot be constant. The only way for the amplitude to rise is if the system gains energy.
This indicates that a horizontal spring's equilibrium position is independent of the mass attached to it.
The same logic applies if you, for example, replace the spring with a stronger one of the same natural length: the equilibrium position will remain unchanged.
Even though the weight must travel longer each oscillation if the amplitude is bigger, the spring produces a stronger force on average, resulting in more acceleration and average speed.
Because the effects of the longer distance and quicker speed balance out, the period of oscillation remains constant!
