1. The problem statement, all variables and given/known data

There is a spring with two crates, (5kg +3 kg) as shown in this picture. (1)

The spring constant is 1000 n/m.

I need to find

a) How much the spring is compressed from its initial position (at rest)

b) The frequency of the oscillation

c) Max amplitude after contact

And then there is a different spring, oscillating horizontally with 2 boxes on top of each other, m1 on m2. The maximum force of friction is define as f.

I need to find the a) max horizontal acceleration for the m1 not to slip on m2 and I need to find the b) max amplitude for simple harmonic motion without m1 slipping. I'm not given any numbers whatsoever.

3. The attempt at a solution

For a) I would think I would do (8)(9.8) and then do that against the force of the constant

b) I think I would use w (frequency?) = (k/m)^1/2.

c) I'm not too sure on this

I don't know what to do afterwards (or at all) for the second spring
