When a mass m= kg is hung on a spring the spring stretches by d= m.
The spring is then stretched an additional m and released, starting the mass/spring
to oscillate.
Determine
a) the spring constant
b) the angular frequency, 
c) the frequency, f of the oscillation
d) the period of the oscillation
e) the amplitude of the oscillation
f) the maximum velocity of the mass
g) the maximum acceleration of the mass
