     A shaft is accelerated from rest at a constant rate to a speed of 3350 rev/min and then is immediately decelerated to rest at a constant rate within a total time of 15.6 seconds. How many revolutions N has the shaft turned during this interval?  Answer: N =^*1 rev  the tolerance is +/-2% 
  
  Solution
(initial velocity - final velocity)* time
(3350-0)*15.6/60=871 rev
N=871 revolutions
