Question

Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 40.0 s to speed up from rest to its top speed of 1 rotation every 1.20 s. The astronaut is strapped into a seat 4.60 m from the axis. What is the astronaut's tangential acceleration during the first 40.0 s ? Express your answer with the appropriate units. How many g's of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.80 m/s2 of acceleration is 1 g. Express your answer with the appropriate units.

Step 1

Given that 1 revolution is equal to 2π radians and it takes 1.2 seconds for 1 revolution, we have: Angular velocity = 2π / 1.2 = 5π / 3 radians per second Show more…
