A particle completes 4 revolution per second on a circular path of radius 0.25m. Calculate the angular velocity of partical

Answer 1

angular velocity is in ... radians per second ... rad/s

there are 2π radians in one revolution

for angular velocity, the length of the radius is immaterial

Answer 2

Va = 4rev/s * 6.28rad/rev = 25.12 Rad/s.
