A 10 g bullet is fired horizontally into a 1 kg block of wood hanging from a 1 m long string attached to the ceiling, getting stuck in the block. Due to the impact, the block then swings on the string to a maximum angle of 60 degrees with respect to the vertical. How fast was the bullet traveling in m/s?
Details and assumptions
The acceleration of gravity is −9.8 m/ss.
You may neglect air resistance.
