Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 20.0 s to speed up from rest to its top speed of 1 rotation every 1.10 s. The astronaut is strapped into a seat 5.60 m from the axis.(adsbygoogle = window.adsbygoogle || []).push({});

A. What is the astronaut's tangential acceleration during the first 20.0 s?

B. What is the astronaut's tangential acceleration during the first 20.0 s?

Part A.

I used [tex] a = a_r + a_t[/tex]

To get a i find velocity, which is [tex] v = d/t , a = v/t[/tex]

for [tex]a_r [/tex] i used [tex] a_r = v^2/r[/tex]

Where did I go wrong ?

Part B.

I've no idea how to do this part, any help is appreciated.
