This problem is*using*real*data*of*the*first*extrasolar*planet*discovered*around *a normal*star*to*calculate*the mass of the planet. I am really stumped on this equation.I put it as an attachment because I had a hard time entering it by keyboard. So far I figured out from graphs and conversions what k, m & P are equal to. k = 62.5 m/s m = 2.11 x 1030 kg P = 379440 seconds But when I get to solving the problem I don’t know where to begin. 62.5 m/s X 2.11 x1030 kg I thought but thats Milliseconds times kilograms. also after that do I change the fraction in parentheses to a decimal and times that by the answer to the beginning part? It is an eight part question and this equation is part 4. If someone could explain how this equation is solved I know I can figure all the other similar equations out. It is an online astronomy class which is why I cannot just go to my instructor and ask. Thank you in advance.
