Question

A turntable is designed to acquire an angular velocity of 32.4 rev/s in 0.5 s, starting from rest.

Find the average angular acceleration of the turntable during the 0.5 s period.
Answer in units of rad/s2

Answer 1

not sure lol

Step-by-step explanation:

ummmmmm look it up on peersanswer.com

Answer 2

Well, the acceleration is the difference of speeds divided by the time period.
`(32.4)/(0.5)=64.8rev/s^2`.
One rev/s is
`2\pi rad/s^2`, so our final result is
`64.8*2\pi=407.15rad/s^2`.
