A plank having mass of 7 9 kg is resting on a smooth horizontal surface and it supports a block of mass 2 kg as shown in figure There is no friction present anywhere The value of the spring constant for the spring shown in the figure is 1000 N m If a bullet of mass 100 grams moving with a velocity of 400 m s hits the plank and gets embedded into it then find the maximum elongation of spring during the motion after the collision
