To calculate the angular velocity of the pulley in question, we apply the formula: ω = 2 * Π * ν = 2 * Π * n / t.
The values of the variables: n – the number of revolutions of the pulley (n = 500 revolutions); t – rotation time (t = 5 s).
Let’s make a calculation: ω = 2 * Π * n / t = 2 * 3.14 * 500/5 = 628 rad / s.
Answer: The sought angular velocity of the pulley in question is 628 rad / s.
