Projectiles - A Realistic Point of View (Linear Drag)
Eddie's Math and Calculator Blog
A challenge for the programmers here perhaps, make an RPN/RPL version. (I used a Casio Prizm for this blog)

On HP50G/RPL, Simple Projectile Motion to begin : « 'a' for 'theta' symbol. Screen shot :
Note that, like with the Prizsm program, Hscale is different of Vscale. You may change the PPAR parameters to avoid distortion (to match the screen resolution)

Thanks, Eddie. nice blog :-)

Hi, I don't understand what are the values that follows the LBL here :
Are they the result of : ρ = P / (R T) ≈ 352.9774471/T ?
I don't found the same values but 1.1922 for 0°C for example... Edited: 16 Mar 2012, 5:42 a.m.

Very nice--especially with l'accent aigu :-) (how do you do that on 48G anyway?) ▼

You mean 'how to produce "accent aigu" and so on ' ? I don't own a 48G but this works on my old 48SX :
Alpha Leftshift E Alpha Leftshift 7 : è (or just the necessary keys if you are Alpha locked. Ex : E Sihft 7 Since 49/50, you can, use CHARS In the previous exemple,i used the excellent HPUserEdit to write the program (and its capacity to produce easily CHOOSE and INFORM structure)

That is very cool--i just tried it. Glad I asked--thanks!

Speaking of coolness, I guess if I want to try running your routine on my 48G I should simply grab the text file and upload it through my good old-fashioned serial cable.....I admit that I haven't actually moved a program to/from my 48G(x) machines in about 4 months... ▼

To drag and drop the text file use this :
%%HP: T(3)A(D)F(.); PS: I don't use here the S~N command :i m not sure it works on a 48G and I change the H and V scale to do 45° is really 45° on the screen (for a 50G resolution) I notice that a 45° throw, is not the longer at all. 30/35° are better (for golf). For baseball seem 15/20°

I assume the fastest and easiest way to transfer a program from HPUserEdit 6 to a 50G would be via the SD card. In what format should I save it from HPUserEdit to the SD card to accomplish this and what would I have to do with the file on the 50G to be able to run the program? Thanks in advance! ▼

To transfer on a real 50G I use an USB cable and the Conn4x software ( it is on the CD with the 50G) Just save the HPUserEdit file without any extension. Then connect Conn4x with you HP50 and drag and drop the saved file in the Conn4x windows. I must say that Conn4X is a very old and awfull program but i don't know a more recent program. I never used a SD card to transfer from PC to HP but i think it s possible.

Looks better if enclosed in PRE tags and wrapped a little: %%HP: T(3)A(D)F(.);

Cool. Next consider lift due to spinning. |
