Question

calculating the angle a ballistic pendulum problem without energy

Answer 1

A bullet with mass m hits a ballistic pendulum with length L and mass M and lodges in it. When the bullet hits the pendulum it swings up from the equilibrium position and reaches an angle α at its maximum. Determine the bullet’s velocity.

Note: The ballistic pendulum was used for measuring the speed of a bullet. It consists of a wooden block suspended from two long cords so that it can swing only in the vertical direction.
