Answer:
Angular velocity of a wheel which makes 20 revolutions per minute is 40π rad/min
Step-by-step explanation:
Angular velocity, ω = 2πf , where f is the frequency.
Here frequency, f = 20 revolutions per minute
Substituting frequency value in angular velocity equation,
Angular velocity, ω = 2πf = 2 x π x 20 = 40π rad/min
So angular velocity of a wheel which makes 20 revolutions per minute is 40π rad/min
