Question

Write a Matlab Function (not a script) that performs a single iteration of the Euler's method for the regular parashot problem, (i.e. just write a function that calculates v_next)
Assume:
cd = 0.25 [kg/m] for t < 10sec and
cd = 1.5   [kg/m] for t ≥ 10sec

Hint: use only if-statements, do not use any LOOPs you only need to compute only one iteration
Hint2: make sure you define the inputs and outputs of the function correctly

Please show how to write this code. (Does not need to be in MatLab, I just need a general idea of how to start)

Answer 1

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

The below bold part is the function and the rest is just to run that function

Euler1(1,1,100,0.1)

function v_next=Euler1(t0,v0,m,h)
v_next=0;
g=9.81;
if(t0<10)
v_next=v0+(g-0.25/m*v0)*h;
else
v_next=v0+(g-1.5/m*v0)*h;
end
end

Kindly revert for any queries

Thanks.
