If a particle moves with a uniform angular velocity ‘ω’ radians/sec along the circumference of a circle of radius ‘r’, the equation for the velocity of the particle, is

v = ω √(y² - r²)

v = ω √(r² - y²)

y = ω √(y - r)

v = ω √(r² + y²)

v = ω √(y² - r²)

v = ω √(r² - y²)

y = ω √(y - r)

v = ω √(r² + y²)
