A cracker is thrown into air with a velocity of 10 m/s at an angle of 45∘ with the vertical. When it is at a height of 0.5m from the ground, it explodes into a number of pieces which follow different parabolic paths. What is the velocity of centre of mass, when it is at a height of 1 m from the ground? (g = 10 m/s^2)

Two men ‘A’ and ‘B’ are standing on a plank. ‘B’ is at the middle of the plank and ‘A’ is at the left end of the plank. Lower surface of the plank is smooth. System is initially at rest and masses are as shown in Fig. ‘A’ and ‘B’ start moving such that the position of ‘B’ remains fixed with respect to ground, then ‘A’ meets ‘B’. Then the point where A meets B is located at
