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.

  1. The coefficient of friction between the blocks and the table is 0.1    
  2. The coefficient of friction between the blocks and the table is 0.2    
  3. If the table was half of its present roughness, the time taken by the block to complete the journey is 4 sec.    
  4. 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 8 sec.

Two smooth balls A and B, each of mass m and radius R, have their centre at (0,0,R) and at (5R,–R,R) respectively, in a coordinate system as shown. Ball A, moving along positive x axis, collide with ball B. Just before the collision, speed of ball A is 4 m/s and ball B is stationary. The collision between the balls is elastic Coefficient of restitution during the collision is changed to 1/2, keeping all other parameters unchanged. What is the velocity of the ball B after the collision?
