Ballistic pendulum
The ballistic pendulum was invented in 1742 by English mathematician Benjamin Robins. A Ballistic Pendulum is a device for measuring a bullet’s momentum and speed by employing perfectly inelastic collision. A large wooden block suspended by two cords serves as the pendulum bob. When a bullet is fired into the bob, it gets embedded in the bob and its momentum is transferred to the bob. The bullet’s momentum and velocity can be determined from the amplitude of the pendulum swing. The velocity of the bullet, in turn, can be derived from its calculated momentum.
After collision, if the pendulum reaches a height h, then from principle of conservation of mechanical energy
where,
m = mass of bullet
M = mass of the bob
vP = velocity of the bob-bullet combination
Now, Momentum before collision = Momentum after collision
where,
vB = velocity of bullet
The ballistic pendulum used to be a common tool for the determination of the muzzle velocity of bullets as a measure of the performance of firearms and ammunition (Nowadays, the ballistic pendulum. has now been replaced by the ballistic chronograph, an electronic device).
Which two principles of Physics are applied to find the velocity of the bullet?
  • a)
    conservation of mechanical energy and conservation of momentum
  • b)
    conservation of mechanical energy and conservation of mass
  • c)
    conservation of mass and conservation of momentum
  • d)
    conservation of mechanical energy, conservation of momentum and conservation of mass
Correct answer is option 'A'. Can you explain this answer?
