what is angular velocity in rad/s of a fly wheel making 300 rpm?

Answer 1

Hey Mate !

Here is your solution :

Given,

A fly wheel makes 300 revolution per minute.

We know that ,

1 revolution = 360°

300 revolution = 360° × 300.

And,

1 min = 60 sec

Now,

= ( 360° × 300 ) ÷ ( 60 s )

= ( 360° × 5 ) /s

=( 1,800° ) / s

Again,

=> 180° = π × 1 radian

=> 1° = ( π × 1 radian ) ÷ 180

=> 1,800° = ( π × 1 radian × 1,800° ) ÷ 180

=> 1,800° = 10 π radian

So,

= 1,800° / s

= 10 π radian / s

Hence, required answer is 10 π as radian / s is already given.

Hope it helps !! ^_^
