Question

B)How many g's of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.80m/s 2 of acceleration is 1 g. Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 30.0s s to speed up from rest to its top speed of 1 rotation every 1.50s s . The astronaut is strapped into a seat 6.30m m from the axis. What is the astronaut's tangential acceleration duing the first 30.0s s ? B)How many g's of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.80m/s 2 of acceleration is 1 g.

Explanation / Answer

As we know that

v = u + at

Here v = wr

= (2pi/t)*r

Therefore , we get equation

(2pi*6.30/1.50) = 0 + a*30

a = 0.8796 m/sec^2

Here centripetal Acceleration = v^2/r

= (2pi*6.30/1.50)^2/6.30

= 110.539 m/sec^2

= (110.539/9.8) g

= 11.28 g
