Can I get matlab code $of$ this?

$1.$ The first type of physical system we will analyze with this approach is an object falling under

gravity in the presence of drag. We know how gravity behaves, but we may not know the drag

coefficient for a given object. For example, assume that we know that an object in free$-$fall

follows the differential equation

$\frac{dv}{dt}=9\mathrm{.}8-v^2$

where $v$ is downward velocity. Assume that an object is released $($so that $v(0)=0)$ and you

measure the following data:

The code dragSolution provided will solve the initial value problem

$\frac{dv}{dt}=9\mathrm{.}8-v^2,v(0)=0$

for a given value of $,$ and will solve it from $t=0$ to $t=T_f.$ Use $T_f=2$ and guess two

different values for the parameter $$ and plot the solution for that $$ along with the data.

Use red circles for the data and a blue line for the solution in each case $($this means you will

be drawing two graphs here, each with two plots on it$).$ How does the value of $$ affect the

velocity over time? For example, if you increase $,$ what happens?

Note: The dragSolution function gives takes two inputs and $T_f)$ and gives two outputs

$(t$ and $v),$ just like the eulerMethod method from a previous assignment. Make sure your

code stores the appropriate variables to get the data you need.

$2.$ The dragOptimization method provided will find the optimal value of $$ by minimizing the

'squared error' between the generated solution and the given data. Use the provided code to

find this optimal value of $$ for the data above. What is the value of $?$ Plot the solution

for that value of $$ with the physical data given $($this will require using the dragSolution

method from the previous part$).$ Do they match exactly?
