Three floats are attached to springs in series as shown in the figure. The un$-$stretched length of each

spring is $1m$ and the volume of each float is $1m^3.$

Determine the amount of stretching of each spring

using the Matrix approach. Solve the problem by

hand and also via MATLAB.

Here, ${}_1,{}_2,$ and ${}_3$ are the smallest, second smallest,

and third smallest non$-$zero digits, respectively, of

your student ID$.$ E$.$g$.,$ ID $=110985247$ gives $a_1=1,z_2=0$

${}_2=2,$ and ${}_3=4.$ please use MATLAB
