The spring block system lies on a smooth horizontal surface. The free end of the spring is being pulled towards right with constant speed v0 = 2m/s. At t = 0 sec, the spring of constant k = 100 N/cm in unstretched and the block has a speed 1m/s to left. The maximum extension of the spring is :
  • a)
    8cm
  • b)
    2cm 
  • c)
    4cm
  • d)
    6cm
Correct answer is option 'D'. Can you explain this answer?
