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?

Answer 1

5g>v^2/r

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

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

solve for RPM

Answer 2

42.77 RPM

Answer 3

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?

Answer 4

Answer is 21 idk why and how

Answer 5

A=v^2/r
5g=50ms^-2
50ms=v^2/10m
V^2=500
V=22.26
