A centrifuge in a medical laboratory rotates at an angular speed of 2650 rpm (revolutions per minute). When switched off, it rotates 59.5 times before coming to rest. Find the constant angular acceleration of the centrifuge. (Assume the initial direction of rotation is the positive direction. Indicate the direction with the sign of your answer.)
N8M.6 A test tube is placed in a centrifuge. When the cen- trifuge rotates at full speed, the test tube's bottom is about 38 cm from the axis of rotation. The material near the bottom of the test tube experiences an apparent effective gravitational force 18 times larger than normal. How many times does the centrifuge rotate per second?
How fast (in rpm) must a centrifuge rotate if a particle 9.00 cm from the axis of rotation is to experience an acceleration of 121000 g's? If the answer has 4 digits or more, enter it without commas, e.g. 13500.
How fast (in rpm) must a centrifuge rotate if a particle 7.6 cm from the axis of rotation is to experience an acceleration of 500000 g 's? Express your answer using two significant figures
How fast (in rpm) must a centrifuge rotate if a particle 9.50 cm from the axis of rotation is to experience an acceleration of 113000 g's? If the answer has 4 digits or more, enter it without commas, e.g. 13500.
The 20-9 centrifuge at NASA's Ames Research Center in Mountain View, California, is a horizontal, cylindrical tube of length 58.0 ft. Another 20-9 centrifuge of length L = 46.0 ft is represented in the figure below. Assume an astronaut in training sits in a seat at one end, facing the axis of rotation 23.0 ft away. Determine the rotation rate, in revolutions per second, required to give the astronaut-a centripetal acceleration of 20.09. L/2 KKKKHIRDI (3) Based on the correct...

1. A centrifuge starts from rest and reaches an angular velocity of 30000 rpm in 5s. What is the angular acceleration(in rad/s2) of this device? 2. A flywheel rotating at 20 rpm undergoes an angular acceleration of 2.0 rad/s2 for precisely 5 revolutions. What is the angular velocity of the flywheel at the end of this acceleration?
