A 345-Kg Centrifuge Takes 100 S to Spin Up from Rest

question 15

Short Answer

A 3.45-kg centrifuge takes 100 s to spin up from rest to its final angular speed with constant angular acceleration. A point located 8.00 cm from the axis of rotation of the centrifuge moves with a speed of 150 m/s when the centrifuge is at full speed.
(a) What is the angular acceleration (in rad/s²) of the centrifuge as it spins up?
(b) How many revolutions does the centrifuge make as it goes from rest to its final angular speed?

Definitions:

Degrees of Freedom

The number of independent values or quantities which can be assigned to a statistical distribution, affecting the shape of the distribution.

P-values

P-values provide the probability of obtaining an effect at least as extreme as the one in your sample data, assuming the truth of the null hypothesis.

Standard Error

A statistic that measures the average distance that a sample statistic, such as the mean, deviates from the actual population mean.

Alternative Hypothesis

A statement that contradicts the null hypothesis and is tested directly in a hypothesis testing framework, assuming the null hypothesis is false.
