As the title said :) I'm trying to find the velocity of a particle with a momentum of between 23 and 150 GeV/c. I found that 1 GeV/c = 5.36 x 10^-19 kg-m/s, and tried to divide by the mass of the particle - this just game me values between 7m/s and some crazy numbers. What am I doing wrong :(

Hi. I perform huge computations worth 70 lines. After those 70 lines, i have these equations in my internal memory. %(stored internally) Wnet=(99*((57443*((4018*y*(66875/(57036*x))^(2528214091580831/18014398509481984))/5 - (57443*y)/50 + (2894969*x^(200/623))/50))/(50*((57443*y)/50 -...

Hi, I need a way to convert kinetic energy into thermal energy as well as the specific heat of the entire Earth's atmosphere. The idea is to see if the heat generated by many meteoroid fragments could possibly account for any climate change. Thanks.
