A ball of mass 0.2 ππ rests on a vertical post of height 5 π. A bullet of mass 0.01 ππ, travelling with a velocity π π/π in a horizontal direction, hits the center of the ball. After the collision, the ball and bullet travel independently. The ball hits the ground at a distance of 20 π and the bullet at a distance of 100 π from the foot of the post. The initial velocity π of the bullet is
