Question

Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 20.0 8 to speed up from rest to its top speed of rotation every 1.20 8. The astronaut is strapped into a soat 4.10 m from the axa Part A What is the astronaut's tangential acceleration during the first 2008? Express your answer with the appropriate units. Value Units Submit Request Part B How many g's of acceleration does the astronaut experience when the device is rotating at top speed Each 9.80 m/s of acceleration is 19 Express your answer with the appropriate units.

Answer 1

elar speed of astronaut w = 21 We 2 = 5.24 rad /s 1-25 Wo = 0 W = 5,24 radls t= 205 using equation w= Wo + at > 5.24 rad/520 +(205) > a = 0.262 radls2 Tangential acceleration of astronaut at = ra Q+= 4.10m x 0.262 rad/s2 at = 1.07 m/s2 ② cento centripetal acceleration of astronacet ac= w2r ac - (5.24 rad/s)'x 4.10 m ac= 11 20 576 m/s2 ac= 112.576m15 xg 9. 8mis la c = 11.48 g
