48. mmh Review Multiple-Concept Example 7 in this chapter 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 0.670 m. At one point on this circle, the ball has an angular acceleration of 64.0 rad/s² and an angular speed of 16.0 rad/s. (a) Find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) Determine the angle of the total acceleration relative to the radial direction.

Transcribed Image Text:48. mmh Review Multiple-Concept Example 7 in this chapter 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 0.670 m. At one point on this circle, the ball has an angular acceleration of
64.0 rad/s² and an angular speed of 16.0 rad/s. (a) Find the magnitude of the
total acceleration (centripetal plus tangential) of the ball. (b) Determine the
angle of the total acceleration relative to the radial direction.
