A centrifuge in a medical laboratory rotates at an angular velocity of 3600 rev/min. When switched off, it rotates through 50.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s^{2}) of the centrifuge.

Step 1

Let the initial and final angular velocities of the centrifuge be denoted as *ω _{o}* and

Let the angular displacement of the centrifuge be denoted as *θ*.

Use the rotational analogue of the third kinematic equation as,

Step 2

Calculate *ω _{o }*and

Step 3

Substitute 0 rad/s for *ωf*, 377 rad/s for *ωo*, 314.16 rad for *&the...*
