it says the solution should look something like this:
{(4z-2,3z-6,z)} where z is any real number
=/

{{6z-4, 5z-5, z}}

I fucking love you both!!!! <3
Thanks Simon and Enk!

Physics question!

A 4.65 kg mass is hung on a spring, and the spring stretches 11.4 cm in response. If the mass is then displaced an additional 5.0 cm and released, what is the period of its motion?

So my formula is T= 2pi * sqrt(m/k)

Where m is mass, and k is the spring force constant.

My trouble is not knowing exactly which numbers to use to find k.

if F= -k * x

then 46 N= -k * x

But what is x? 5 cm, 11.4 cm, or 16.4 cm?

If the spring is displaced away from the equilibrium, you need the sum of the displacement and the rest state with the weight. This means the total of the two. Also, looking at your formulae, I have noticed that your Newton measurement is incorrect.

That was my friend. Also, isn't one of your characters named Physic?

From the book I'm using, Force=mass*accel.
Gravity is the acceleration, so 4.65kg*-9.8m/sec^2 = -45.5 N, which rounds to -46 N.

I think the equilibrium is supposed to be at 11.4cm. The question is worded poorly, but I think the first and second sentences are separate. So, the mass is hung from a spring, comes to a rest and then is pulled down.
