Answer:
Given:
Linear Velocity = 20 m/s
Diameter of the circle = 10 m
To Find: Angular Velocity of ball
Calculation:
Angular velocity in a circular motion is linear velocity upon radius of the circle.
Radius of the circle = r = = 5 m
Expression for angular velocity is expressed as:
v = ω * r, where ω is the angular velocity, v is the linear velocity and r is the radius of circle.
ω = 4
Answer:
Angular velocity of the ball is 4 .
