Mass as a function of time only

This is everything

Thank you. The only undefined parameter is m(0). The linear units will be meters. As for the rate of loss of mass, I have it from here: 1951ApJ...113..475C Page 475 I may have integrated it wrongly. Could it be that I'm missing a constant, m(0), in the equation? ζ is the energy needed to...

Thanks! Managed to find this...

Hi! I am to model the motion of a meteor as it travels through the atmosphere, taking into account the loss of mass, which is 0.025 kg upon impact (height = 0). I also have to take into account the air resistance on the meteor, the fact that the air density is a function of height and that the...

Thanks! Just what I needed.

How do I find the heat transfer coefficient for a meteorite? The meteorite is made of carboneus chondrite, but approximations with heat transfer coefficients for regular stones or rocky materials would be just as fine. Furthermore, how would I calculate the energy required to vaporize 1 g of...

I'll definitely keep that in mind. Just for the fun of it, here's a video of the meteor my project is based upon (and it's frames from this video, that I've based my calculations of its velocity on):

In any case, thank you for your help so far!

I see. My problem is that I am to model the motion a meteorite as it travels through the atmosphere, and I am working with a very limited number of pages. This is what I know: Stony meteorite, specific heat: c_sm = 1.2 * 10^3 J kg^-1 K^-1 Stony meteorite, thermal conductivity: k_sm = 2.0 W m^-1...

Great! Very helpful.

Is there a general or approximative equation for the loss of mass, of a meteorite as it travels through the atmosphere? For example as a function of something like its speed, surface area, the drag force experienced by the meteorite.

Thank you very much, truly helpful. Lastly; is it possible for you to list some references or link some pages, that concern this Newtonian impact theory or Newton's original theory of fluid motion?

I have no background in aerodynamics, I have physics in high school (in Denmark). I ask, as I am to model the motion of the meteorite as it moves through the atmosphere, and as it not only moves at a supersonic speeds, but at more than 3 times the lower limit of re-entry speeds (according to...
