A simple pendulum of length 1 m has a wooden bob of mass 1 kg. It is struck by a bullet of mass 10 –2 kg moving with a speed of 2 × 10 2 ms –1 . The bullet gets embedded into the bob. The height to which the bob rises before swinging back is (use g = 10 m/s 2 )

1. 0.20 m
2. 0.35 m
3. 0.30 m
4. 0.40 m

Correct answer: 0.20 m
