A discus thrower accelerates a discus from rest to a speed of 25.2 m/s by whirling it through 1.24 rev. Assume the discus moves on the arc of a circle 0.98 m in radius. A discus thrower moving in a circle as he prepares to throw the discus.
(a) Calculate the final angular speed of the discus.
What is the relationship between the angular velocity and the linear speed of a point on the edge of the circle? rad/s
(b) Determine the magnitude of the angular acceleration of the discus, assuming it to be constant.
You know the distance (angle) traveled and the final (angular) speed in a constant (angular) acceleration problem. How do you determine the acceleration in this case? rad/s^2
