## Homework Statement

A block of mass 5 kg is attached to a spring of 2000N/m and compressed a distance of 0.6m. The spring is then released and oscillates.

a. what are the period, frequency, and angular frequency

b. what is the energy in this system

c. what is the maximum velocity

## Homework Equations

period=1/frequency

d^2x/dt^2 + (k/m)x = 0

[tex]\omega[/tex]= (2*pi)*frequency= 2pi/period= sqrt(k/m)

E= 1/2mv^2 + 1/2kx^2= 1/2kA^2
