and the looser guy down there writing something about protocol, doesn't at all mean my question is being answered...

The force of gravity is a red herring. Since everything is horizontal and frictionless the force of gravity plays no role.
All of the answers with "g" involved can be ignored.
One approach would be to set the kinetic energy of the moving mass equal to the potential energy stored in the spring as it is compressed.
1/2 M V^2 is the kinetic energy.
Force times distance is equal to energy. Since the force being applied by the spring is changing overtime one either needs calculus or a sense of symmetry that would allow some averaging process to be found.
Hooks law of springs says that the force is proportional to the distance of compression. That means that the sum of the force exerted in the first 100th of an inch added to the force exerted in the last 100th of and inch is equal to the force exerted at the mid point of compression times two. The average force times the distance compressed is equal to the energy stored in the spring.
The average force is half the total distance compressed times the spring constant K.
1/2KD^2=1/2 MV^2
D^2=M/K*V^2
D=sqrt(M/K)*V

Yes, it is a URL, or uniform resource locator. It represents a protocol and a domain address for a file that can be found on the internet. It is shown in the form of a hyperlink, meaning that you can click on the text and your web browser will try to open the file at that location.
