Question

A centrifuge is used to test space pilots. The centrifuge spins with a

centripetal acceleration of 6.55 g. If the length of the centrifuge's arm is 18 m,
what is the speed of the centrifuge?

Answer 1

34 m/s

Step-by-step explanation:

Answer 2

34 m/s

Step-by-step explanation:

Centripetal acceleration is:

a = v² / r

Given a = 6.55 × 9.8 m/s² = 64.2 m/s², and r = 18 m:

64.2 m/s² = v² / (18 m)

v = 34 m/s

The speed of the centrifuge is 34 m/s.
