Question

In the track shown in figure section AB is a quadrant of a circle of 1 metre radius. A block is released at A and slides without friction until it reaches B. After B it moves on a rough horizontal floor and comes to rest at distance 3 metres from B. What is the coefficient of friction between floor and body ?

  1. 1/3    
  2. 2/3    
  3. ¼    
  4. 3/8    

The correct answer is: 1/3
