a steel spring that it extends by 10cm in equilibrium when you attach the upper end of the spring to a fixed support and hang a weight of 100g at the lower end.
And I found k and T, so how about if I change the weight to 1kg at the lower end and do the same thing?
F = -kx
The Attempt at a Solution
I found they actually same.
T=2pi*sqrt(m/k) = 2*pi*sqrt(0.1/9.81) = ...
k = 98.1
T=2pi*sqrt(m/k) = 2*pi*sqrt(1/98.1) = ...
I think I did wrong, who can help me?
