Question

A disc is rotating with angular velocity 5 Rev/sec. It comes to rest in 10 seconds. How many revolutions did it turn before stopping

Answer 1

Answer:-

• Angular velocity=$\omega$=5rev/s
• Time=t=10s

We know

$\boxed{\sf Total\:revolutions=\omega t}$

$\\ \sf\longmapsto Total\:revolutions=5\times 10$

$\\ \sf\longmapsto Total\:revolutions=50$
