Question

A spring block system is placed on a rough horizontal floor. The block is pulled towards right to give spring some elongation and released

  1. The block may stop before the spring attains its mean position    
  2. The block must stop with spring having some compression    
  3. The block may stop with spring having some compression    
  4. It is not possible that the block stops at mean position    

The correct answer is: The block may stop before the spring attains its mean position
