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.

None of these equations exactly answer the problem, one of them doest mention when a mass is added to the end, but it requires you using Frequency, while I dont have the frequency...
After watching a lecture on that wikipedia page he explained the equation:

T= 2Pie sqroot(m/k)

This will solve my problem nicely, thank you!
