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.
