Question

A centrifuge in a medical lab rotates at an angular velocity of 3600 rev/min. when switched off it rotates through 50 revs before coming to rest. find the constant angular acceleration of the centrifuge in rad/s2

Answer 1

To find the constant angular acceleration of the centrifuge, you can use the formula for angular acceleration and substitute the given values.

Step-by-step explanation:

Angular velocity is the rate of change of an object's angular position with respect to time. It is usually measured in radians per second (rad/s). In this case, the centrifuge rotates at an angular velocity of 3600 rev/min. To find the constant angular acceleration, we can use the formula:

Angular acceleration = (final angular velocity - initial angular velocity) / time

Given that the centrifuge rotates through 50 revs before coming to rest, we can convert this to an angular displacement by multiplying it by 2π radians per revolution. We can then substitute the values into the formula to find the constant angular acceleration.
