Question

Review the multiple-concept example as an aid in solving this problem. In a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves on a circle. In one instance, the radius of the circle is 0.639 m. At one point on this circle, the ball has an angular acceleration of 63.7 rad/s2 and an angular speed of 16.3 rad/s. (a) Find the magnitude of the total acceleration (centripetal plus tangential) of the ball. m/s2 (b) Determine the angle of the total acceleration relative to the radial direction.

Explanation / Answer

a) total accelration = 420.6 b) angel = 8.7 degrees
