Question

A centrifuge is used to test space pilots. The centrifuge spins with a centripetal acceleration of 3.04 g. If the length of the centrifuge's arm is 21 m, what is the speed of the centrifuge?

Answer 1

Centripetal force =\[\frac{ mv ^{2} }{ r }\]

You know F=ma

so combine the equations for force - this eliminates m

solve for v

Answer 2

Yes and 1 g = 9.8 m/s^2,
and you are asked for 3.04 g
