Astronauts are spun in a device called a centrifuge as a physical test before they fly in space. With what linear speed would an astronaut need to be spinning in order to experience an acceleration of 3 g's at a radius of 10.0 m? (1 g = 9.80 m/s^22)
A 75.0 kg astronaut is training for accelerations that he will experience upon reentry. He is placed in a centrifuge (r = 20.0 m) and spun at a constant angular velocity of 15.0 rpm (revolutions per minute). He is then slowed and brought to a stop in 2.0 minutes. a. Find the magnitude and direction of the centripetal acceleration and force when he is spinning at constant angular velocity. b. How many g’s is the astronaut experiencing when moving at...
