Homework 2 Problem 2

=Part A=

//Main Focus: Can you solve a system of linear equations using the Reynolds equation.//

Solve F = d/dt∫pvx•dVol + ∫pvx(v•n)dS  Since this is steady and not fluctuating with time (only Force), this equation simplifies to:  F = m1•v1 + m2•v2  Plug this into the equation for m2 and you will get:  m2 = km1/(1+kv1/v2) =

Part B=

//Main Focus: Can you solve for k.//

I suggest solving for k **before** you plug your numbers in as I think it will be the easiest way to solve this problem.

You should end up with:

k = m2/(m1-m2v1/v2) k = 6.67
