Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 40.0s to speed up from rest to its top speed of 1 rotation every 1.40s . The astronaut is strapped into a seat 4.50m from the axis. What is the astronaut's tangential accelera...

I can do the work, just need the formulas!

this is wierd to write but ill do my best. 12 4 square root 2 (the 4 is on top of the radical if that helps) - 7 4 square root 312 (again the 4 is on top of the radical) if this is confusing ill try to break it down more. thank you
