2. a 75.0 kg astronaut is training for accelerations that he will experience upon reentry. he is placed in a centrifuge (r = 10.0 m) and spun at a constant angular velocity of 15.3 rpm. answer the following: a. what is the angular velocity of the centrifuge in rad/s? b. what is the linear velocity of the astronaut at the outer edge of the centrifuge? c. what is the centripetal acceleration of the astronaut at the end of the centrifuge? d. how many g’s does the astronaut experience? e. what is the centripetal force and net torque experienced by the astronaut? give magnitudes and directions.

Avalue that describes how heavy an object is and is related to the force of gravity is

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
