# Problem: A bullet of mass 24 g is fired into the bob of a ballistic pendulum of mass 2.85 kg. When the bob is at its maximum height, the strings make an angle of 40° with the vertical. The length of the pendulum is 3.75 m. Find the speed of the bullet (in units of m/s). The acceleration due to gravity is 9.81 m/s2 .
