## Homework Statement

Suppose that I hang a 100 gram mass from a spring. When I do this, I find that the srping stretches 10 centimeters.

1)What is the gravitational force on the mass that I hang from the spring? give your answer in Newtons

2)what is the force that the spring is exerting on the mass?

## Homework Equations

F=-ky

F=mg

## The Attempt at a Solution

ok so I figured most of the problem out, I know that its a simple problem but I am just stuck on the first part and don't really know how to begin the second question. What I did was use the two equations i gave to solve for g=-ky/m but my problem is i don't know what k is or how to get it. As for the second part, i just have no idea how to start it. Thanks for any help in advance.
