A softball pitcher swings a ball of mass 0.244 kg around a vertical circular path of radius 59.3 cm before releasing it from her hand. The pitcher maintains a component of force on the ball of constant magnitude 30.3 N in the direction of motion around the complete path. The speed of the ball at the top of the circle is 14.7 m/s. If the ball is released at the bottom of the circle, what is its speed upon release

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 in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 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.
