A bullet of mass m fired at
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 emerges out with half the kinetic energy it had before hitting the target:
Which of the following statements is correct in respect of bullet after it emerges out of the target?
Text Solution
Verified by ExpertsC
: Let v’ be the velocity of the bullet after emerging from the target.
Kinetic energy of the bullet emerging from the target


i.e. velocity is more than half of its earlier velocity. As the bullet loses some of its vertical velocity component therefore, velocity on emerging from the target changes.
The bullet will move in a different parabolic path.
