Question
The velocity time graph of the fig. shows the motion of a wooden block of mass 1 kg which is given an initial push t = 0, along a horizontal table.
- The coefficient of friction between the blocks and the table is 0.1
- The coefficient of friction between the blocks and the table is 0.2
- If the table was half of its present roughness, the time taken by the block to complete the journey is 4 sec.
- If the table was half of its present roughness, the time taken by the block to complete the journey is 8 sec.
The correct answer is: If the table was half of its present roughness, the time taken by the block to complete the journey is 4 sec.
