## Homework Statement

Fluid Mechanics problem: http://i.imgur.com/dlAO6.jpg

SHM of spring problem: http://i.imgur.com/7AOMR.jpg

## Homework Equations

Fluid mechanic problem;

Bernoulli's principle A

_{1}v

_{1}=A

_{2}v

_{2}

v= velocity

A= cross sectional area

R= flow rate

SHM of spring problem;

x(t)=Acos(ωt+∅)

## The Attempt at a Solution

For the Fluid problem I ended up with :

v = R/A

_{2}= 2R/A

_{1}

For the SHM problem I ended up with:

A = 0.10

∅= cos

^{-1}0.05/0.1

I'm having a problem with both of these problems and I'm not confident with my answers.

Any help would be greatly appreciated :)

(And sorry if I break any rule of the forums or such, It's only my first post :/ )
