Question

A fly wheel completes 200revloutiins per minute calculate its angular speed ????​

Answer 1

Answer:

Given that,

n=120rpm

n= 60/120

n=2

Now, we know that

ω=2πn

ω=2π×2

ω=4πrad/s

Hence, the angular velocity is 4πrad/s.

Answer 2

Answer:

Given that,

n=200rpm

n=

60

200

n=0.3

Now, we know that

ω=0.3πn

ω=0.3π×2

ω=0.6πrad/s

Hence, the angular velocity is 0.6πrad/s
