## Homework Statement

A spring with a spring constant of 1.8 X 102 N/m is attached to a 1.5 kg mass and then set into motion.

a. What is the period of the mass-spring system?

b. What is the frequency of the vibration?

## Homework Equations

The only one that comes to mind would be Hooke's Law

Fe = -kx

## The Attempt at a Solution

The issue is that it gives a mass, but neither displacement, nor Felastic, which makes me wonder whether I'm using the wrong equation, or I'm not fully understanding the equation, as the only variable I have here that fits is -k (spring constant), unless of course Felastic can be related to Fg (MG) in some way.
