Okay i know that L = Iw and L = r x p I can use equation of motion to find W.and I=wrp2 but how will that get me to the answer? i have tried everything and the answer i get everytime is 12 or 18.. Both of them are not one of the choices. I have a test tonight and have to go to work right before the test so if anyone of you can please help me. I would really appreciate it. Another question i needed help with is So what i thaught on this question was to take the earth's mass and diameter to be 1 so the mass of venus would be Mass(venus)=0.0558xMass(earth) Mass(venus)/Mass(earth)=0.0558 is this the correct aproach? i got the right answer at the end and just want to know if i was doing it right?
