A horizontal spring is fixed at one end, then stretched 3.0 cm by a force of 6.0 N.
Afterwards, a 0.50 kg body is attached, pulled 2.0 cm from its rest position, and
released. Find
(a) spring constant,
(b) angular frequency,
(c) frequency and
(d) period.

k = (Force)/(deflection) in N/m
w = sqrt(k/m) in radians/sec
if mass m is in kg
f = 2 pi w
Period = 1/f
You really need to learn these formulas and not have someone keep reminding you.
