The problem involves a mass of 40 grams attached to a vertical spring with a spring constant of 20 N/m. The objective is to determine how much the spring is stretched when the mass is lowered slowly until the spring stops stretching.
Participants are actively engaging with the problem, with some offering hints about calculating weight and gravitational force. There is a recognition that the mass's weight can be determined using the formula F = mg, and the implications of the mass being lowered slowly are being considered.
The discussion includes considerations about the acceleration of the mass and its effect on the forces involved, as well as the assumption that the spring is in equilibrium when it stops stretching.
Yes!ajmCane22 said:Would it be F = mg?
mg gives the weight of an object regardless of its acceleration. (If the object were dropped, so that the only force acting was gravity, then its acceleration would be g.)It said the spring was lowered slowly so I assumed the acceleration was slower than gravity.
