    Having a hard time solving equation for mass of planet

    When you click on the graph it tells you the specifics of where you click. you just have to click within a margin of what they want. which I missed on K. K actually equals 55 m/s. Luckily they let you keep trying till you get it right or give up and submit it. So I just have to rework the...

    Having a hard time solving equation for mass of planet

    I should have probably given you this information too. The relationship between the mass of the unseen planet in kilograms, the semiamplitude K in meters per second, and the period P in seconds This equation can be solved to give mp sin i. (Remember, the mass of the planet is usually...

    Having a hard time solving equation for mass of planet

    Here is a shot of question and graph. I figured out what steps to take but I have some questions on some of them.. I don't know how to calculate to a fractional power like 2/3 or 1/3 power of. Calculate M^(2/3) = (Result 1) Multiply K times Result 1 (which calculates K * M^(2/3)) = (Piece...

    Having trouble figuring center of mass between Sun and Jupiter

    Thank you so much for your help! I just checked my first answers and they are correct. R= 1048 d1 d1= 742652.67 km

    Having trouble figuring center of mass between Sun and Jupiter

    OK so that makes sense. So then part a would be R= 1048 d1 So then if R (the total distance between the Sun and Jupiter) is 7.783 x 108 km, what is d1 in km? Would you take 778300000 and divide by 1048?

    Having trouble figuring center of mass between Sun and Jupiter

    Well I figured m1 = 1,047 and m2 = 0 since the Sun is 1,047x larger than Jupiter. Then I took d1 as 1 and d2= 1/1,047 which is .000955. But R= 1.000955 d1 doesn't seem right at all. I think I am plugging the wrong numbers into the equation.

    Having trouble figuring center of mass between Sun and Jupiter

    I am taking an astronomy class because I am interested in it and wanted to know more. I love all I am learning unfortunately my math skills are holding me back from getting all that I can out of this class. I realize this might not be the toughest math problem but can someone explain help me out...
