A bullet of mass m is fired at an angle of 180° to the horizontal and leaves the barrel of the gun with a speed u. During its motion, the bullet hits a soft target at a height h above the ground. The bullet emerges from the target with half the kinetic energy it had before hitting the target. How many of the following statements are correct regarding the bullet after it emerges from the soft target? (I) The speed of the bullet will be more than half of its earlier speed. (II) The speed of the bullet will be reduced to half of its initial speed. (III) The bullet will fall vertically after hitting the target. (IV) The bullet will continue to move along the same parabolic path. (V) The bullet will move in a different parabolic path. (VI) The internal energy of the particles present in the soft target will increase.
