Which of the following objects in motion has the highest inertia? A.) A 5.0 kg mass moving at 2.0 m/s

B.) A 8.0 kg mass moving at 9.0 m/s

C.) A 6.0 kg mass moving at 10. m/s

D.) A 15 kg mass moving at 2.0 m/s

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.
