Hi: Please Anyone Help me urgently, i need the simple code and little comments, I will be very thankful,,,,

Hi:

Respected Sir!

I am having trouble in writing the code.

I need the code:

1.Calculate the trajectory of a projectile, both without and with an air-friction function term that depends on v. Explore the dependence of the range on various variables.

2. Add a variable amount of v2 air friction to the force.

3. Change the problem to a three-dimensional baseball problem, adding the magnus force term for a ball with angular velocity pointing in the y (away from the earth) direction. Plot 2-d projections of the trajectories

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

Please check it out

I have tried

function [x,y]=trajectory(a,time)
x0=0
y0=0
k=0
angle=a*(pi./180)
v=70
g=9.81
t=0:0.1:time
x=x0+v*cos(angle)*t;
y=y0+v*sin(angle)*t-(g*t.^2)/2
figure
plot(x,y)
end

Respected Sir:

If you have time please help me i would be very thankful to you

It is good that you now added your code and some notes, but you still haven't asked a specific question.

I would also suggest removing the word urgent from your title. Your question is not urgent, the reason for that is explained here.

Did you search for projectile in this forum? I've posted my projectile demo countless times. It's attached again. It computes just about everything you could want to know. It doesn't do drag though - you'd have to add that.
