A centrifuge in a medical laboratory rotates at an angular speed of 3,450 rev/min. When switched off, it rotates through 54.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.

Cheryl is riding on the edge of a merry-go-round, 2m from the center, which is rotating with an increasing angular speed. Cheryl’s tangential acceleration is 3.0m/s2. At the instant that Cheryl’s linear speed is 4.0m/s, what is Cheryl’s total acceleration?

A centrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. When switched off, it rotates through 54.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.

A floppy disk rotates with a constant angular speed of 60.6 rad/s. Find the tangential speed at a point 0.073 m from the axis of rotation. What is the magnitude of the centripetal acceleration at this point?

Human centrifuges are used to train military pilots and astronauts in preparation for high-g maneuvers. A trained, fit person wearing a g- suit can withstand accelerations up to about 9g (88.2 m/s2) without losing consciousness. HINT (a) If a human centrifuge has a radius of 5.17 m, what angular speed (in rad/s) results in a centripetal acceleration of 9g? X rad/s (b) What linear speed (in m/s) would a person in the centrifuge have at this acceleration? m/s

A centrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. When switched off, it rotates through 52.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.

A flywheel slows from 517.7 rev/min down to 364.9 rev/min while spinning through 44.4 revolutions. What is the angular acceleration of the flywheel (in rad/s/s)? Assume that the flywheel slows down at a constant rate.

A centrifuge in a medical laboratory rotates at an angular speed of 3,650 rev/min. When switched off, it rotates through 52.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.

A child sits on a merry-go-round that has a diameter of 4.00 m. The child uses her legs to push the merry-go-round, making it go from rest to an angular speed of 17.0 rpm in a time of 43.0 s. What is the average angular acceleration aavg of the merry-go-round in units of radians per second squared (rad/s?)? davg = rad/s2 What is the angular displacement Að of the merry-go-round, in units of radians (rad), during the time the child pushes the merry-go-round?
