SUMMARY

The discussion focuses on solving the "Momenergy Problem" in physics homework, specifically addressing the calculation of kinetic energy using the formula E_k = Mv^2/2. The user attempts to compute the energy with values M = 2*5E6 and v = 42, resulting in E_k = 8.8E9 J. Additionally, there is a need to convert mass from kilograms to milligrams for the final solution. The conversation emphasizes the importance of unit conversion in physics calculations.

E_k = Mv^2/2 = 2*5E6*42^2/2 = 8.8E9J = mc^2

solve for little m which will be in kg so you must convert to milligrams.
