1. The problem statement, all variables and given/known data
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

2. Relevant equations
period=1/frequency
d^2x/dt^2 + (k/m)x = 0
$$\omega$$= (2*pi)*frequency= 2pi/period= sqrt(k/m)
E= 1/2mv^2 + 1/2kx^2= 1/2kA^2

3. The attempt at a solution
I have not been able to attempt a solution because I do not know where to start. Please help.
