Question

A cylinder having radius 0.4 m, initially rotating (at t = 0) with w0 = 54 rad/sec is placed on a rough inclined plane with q = 37° having friction coefficient m = 0.5. The time taken by the cylinder to start pure rolling is :

  1. 5.4 sec    
  2. 1.4 sec    
  3. 1.2 sec    
  4. 1.8 sec    

The correct answer is: 1.8 sec
