Compute the each part of given question:
Question: Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 16.0 seconds to reach top speed, which is 1 revolution per 1.20 s. The astronaut is strapped into a seat 4.30 m from the axis.
Part I: What is the astronaut's tangential acceleration during the first 16.0 s?
Part II: How many g's of acceleration does the astronaut experience when the device is rotating at the top speed? Each 9.80 m/s2 of acceleration is 1 g.
