For the Gravitron ride above, assume it has a radius of 18 m and a centripetal acceleration of 32 m/s?. Assume a person
is in the graviton with 180 cm height and 80 kg of mass. What
is the speed it is spinning at?
a 24 m/s
b 17 m/s
7
C 32 m/s
d 9.8 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.
