    How Does Angular Acceleration Affect Spacecraft and Clock Movements?

    The moon orbits Earth in 27.3 days. suppose a spacecraft leaves the moon and follows the same orbit as the moon. if the spacecraft has a constant angular acceleration of 1.0 X 10^ -10 rad/s 62 what is its angular speed after 12h of flight? (Hint: At take off the spaceship has the same...

    How Does Earth's Moment of Inertia Reflect Its Mass Distribution?

    Thank you! Thank you to everyone that responded to these two problems. All of your suggestions and imput were very helpful. when i answered these questions the first time i was greatly confussed and just had to guess but with each one of you giving me a little hint or something to think about it...

    How Does Earth's Moment of Inertia Reflect Its Mass Distribution?

    [FONT="Comic Sans MS"]The moment of inertia of Earth was recently measured to be 0.331MR^2. what does this tell you ablut the distribution of mass inside the earth? that was the problem my attempt/answer was that it tells us that it is widely distributed because Earth is so large and round...

    Torque on crane arm and load limit

    first off i want to thank you for taking the time to try to help me out. secondly so the answer for part a should be 6342.93 N m?? why do you use cos instead of sin? thirdly i do not understand what you are talking about in part b. what angle would i use? am i suppose to use cos instead of...
