This was an art trade with :iconzephyter0:!

I experimented heavily with this image and am for the most part happy with the results. This is 100% Paint Tool SAI. Hopefully I can tighten up the technique and bring about better results with the next image.

Yes... why? What does that have to do with this post?

I can't think of anyone who can calculate the correct trajectory to set that sling at for this mission.

Good job

> calculate the correct trajectory to set that sling at


1) Let x and y be on an imaginary plane, such that the slingshot is coincident with both this plane and with the y-axis, and such that Rainbow Dash and the launch point both lie on this plane. The origin (0,0) will be at the launch point, and the positive x-axis will point toward RD and be parallel to the ground.

2) Assuming the slingshot behaves as an ideal linear spring, and assuming we know both the elastic's stiffness (k, in N/m) and Pinkie's mass (m, in kg), find the initial launch speed (v, in m/s) by relating it to "distance stretched back" via spring energy transferring to kinetic energy: PE = KE --> 0.5*kx2 = 0.5*mv2, v>0 .

3) Several boring rearrangements of various projectile motion equations gives us this equation. Assuming we know Dash's x-y coordinates relative to the origin (i.e. her distance from and height above the launch point), and assuming g = -9.81 N/kg, we can find the correct trajectory (i.e. angle θ) to launch Pinkie at.

Thanks for giving me a brain exercise, bro. :iconbrohoofplz:

Well, Pinkie Pie is... Pinkie Pie, and thus indestructible, so even if they miss it's no problem.

As for Rainbow Dash... I have only pity.

Why? Pinkie's just tackle-hugging long distance...via slingshot...

Okay so I can see one way this might go wrong

That is quite possibly the most specific plan I have even seen.
