SUMMARY
The angular velocity of a ball with a mass of 0.25 kg, whirled in a horizontal circle with a string length of 0.03 m, completing 5 revolutions per second, is calculated using the formula angular velocity = 2πF. This results in an angular velocity of 31.4 radians per second. It is crucial to note that the units of angular velocity are radians per second, not meters per second. The relationship between angular velocity and linear velocity is established by multiplying angular velocity (ω) by the radius (r).
