01The brief

Computing for EngineersUndergradDue in 3 days

Projectile motion with air drag

Solve the 2D equations of motion for a projectile with quadratic drag using ode45, stop at impact, compare range with the no-drag case and plot both trajectories.

Requirements

State vector [x y vx vy]
ode45 with an impact event
Compare range with and without drag
Labeled trajectory plot

02The solution

projectile.m15 lines

1% projectile with quadratic drag, solved with ode45

2g = 9.81; k = 0.002; % drag constant per unit mass

3v0 = 50; theta = deg2rad(40);

4s0 = [0; 0; v0*cos(theta); v0*sin(theta)];

6rhs = @(t, s) [s(3); s(4);

7 -k*norm(s(3:4))*s(3);

8 -g - k*norm(s(3:4))*s(4)];

10opts = odeset('Events', @(t, s) deal(s(2), 1, -1));

11[t, s] = ode45(rhs, [0 20], s0, opts);

13plot(s(:,1), s(:,2), 'LineWidth', 1.5); hold on

14xlabel('x (m)'); ylabel('y (m)');

15fprintf('Range with drag: %.1f m\n', s(end,1));

03The explanation doc

The state vector

Position and velocity together make the system first-order, which is what ode45 needs.

Stopping at impact

The event function fires when y crosses zero going down, so the solver stops at the ground.

Result

Drag cuts the range from 251.0 m to 196.4 m with these parameters.

How it works

From upload to predicted budget in under a minute.

The AI does one job: it predicts your price. A senior engineer reviews your files and sets the final number.

01
Step 1 of 4
Upload your files
Prompt, rubric, starter code, or a screenshot of the task. PDF, DOCX, ZIP, code or images, in any mix.
02
Step 2 of 4
The AI asks what’s missing
It confirms your due date, then asks up to 3 questions your files don’t answer. Each one has an “I don’t know” option.
03
Step 3 of 4
See your predicted budget
A price range appears right away. No email, no sign-up.
04
Step 4 of 4
A senior engineer confirms your price
Leave your email. Within 5 minutes you get one fixed price. It never goes above the top of your range.

No payment to get a price. You pay only after you accept the fixed price. If the AI can’t price your files, an engineer emails you a price instead.

Guarantees

Every order is covered. In writing.

Full refund, in three cases

We miss your deadline. Your code still doesn’t meet your original brief after revisions. Or you cancel before an engineer starts.

Partial refunds, worked out in the open

Cancel after work starts, or keep part of the work: we refund the rest and show you how we worked it out first.

Refunds that move fast

We reply within 24 hours. Approved refunds go back to your card through Stripe within 2 business days.

Unlimited revisions for 14 days

We revise until it matches your original instructions. No fees.

Your price is capped

Your fixed price never goes above the top of your range.

How the cap works

NDA and privacy

Your name, school and files are never shared, sold or reused. Engineers never see your name or email.

Secure payment

Processed by Stripe. We never see or store your card details.

FAQ

Questions students ask first.

Still have a question?

Email us any time. Support runs 24/7 and a real person replies.

team@domyprogramminghomework.io

Which MATLAB version?

Tell us yours. We avoid functions newer than your release so nothing breaks.

Can you use Octave?

Yes. If your course uses GNU Octave, we test there and skip MATLAB-only toolboxes.

Do you write the lab report?

You get figures, results and an explanation doc to learn from. Graded write-ups should be your own.

Is the predicted budget the final price?

Not exactly, but it’s capped. Our team reviews your files and sends one fixed price before you pay anything, and it never goes above the top of your range.

What if you miss my deadline?

You get a full refund, back to your card through Stripe. It’s in our refund policy, in writing.
