Q: A bullet of mass m fired at 30° to the horizontal leaves the barrel of the gun with a velocity v. the bullet hits a soft target at a height h above the ground while it is moving downward and emerge out with half the kinetic energy it has before hitting the target. Which of the following statements are correct in respect of bullet after it emerges out of the target?
(a) The velocity of the bullet will be reduced to half its initial value
(b) The velocity of the bullet will be more than half of its earlier velocity
(c) The bullet will move in a different parabolic path
(d) The internal energy of the particles of the target will increase
Ans: (b) , (c) & (d)
