A cracker is thrown into air with a velocity of 10m/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 1m from the ground? (g=10m/s^2)
