Extension of spring A:

Neutral: 52 cm

1 N: 41 cm

2 N: 30 cm

F = kx

**k = 9.1 N/m**

10 oscilliations = 9.26 seconds

Calculating the theoretical period for 2 newton:

t=2pi*sqrt(m/k)

t=2pi*sqrt(2/9.1)=

**2.9**which is completely wrong compared to the real life result.

If i set k to 91 instead of 9.1 the resulting period is 0.93, much closer to reality.

Have I botched up the units along the way or what have I done wrong?

I'd be very greatful for help.
