Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 25 seconds to reach top speed, which is 1 revolution per 1.2 s. The astronaut is strapped into a seat 5.5 m from the axis.
a. What is the astronaut's tangential acceleration during the first 25 s?
b. 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.
