an astronaut rotates at the end of a test machine whose arm has a length of 10.0m. if the acceleration she experiences must not exceed 5g (g=10m/s^2? what is the maximum number of revolutions per minute of the arm?

  • physics - ,

    5g>v^2/r

    and v=RPM*1min/60sec * radius

    5g>RPM^2 * 1/3660 * r

    solve for RPM

  • physics - ,

    42.77 RPM

  • physics - ,

    I did what Bob did and got 134 rpm, which is wrong and crazy fast, but Jay's answer is only twice what the answer should be. What did you do?
