Question

Calculate the angular acceleration if a flywheel
gains a speed of 540 rp.m. in 6 seconds.
​

Answer 1

Answer:-

• Angular momentum=540rpm
• Time=6s

We know

$\boxed{\sf Angular\:Acceleration=\dfrac{Angular\:Momentum}{Time}}$

$\\ \sf\longmapsto Angular\:Acceleration=\dfrac{540}{6}$

$\\ \sf\longmapsto Angular\:Acceleration=90rads^{-1}$
