Apulley with the radius of 10.0 cm was connected to a motor with a massless
string. the motor turns at the rate of 15000 rad/s. then the motor slow the
turning uniformly to 1 rad/s in 9s. calculate :
(i) the angular acceleration
(ii) the number of turn have been made within that period.
(iii) the length for the string that encircles within that period.
(iv) the tangential acceleration for that string.
(v) the extra time needed for the pulley to stop turning.

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.
