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.

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
