JEE Main 2024 Physics question
A simple pendulum of length 1 m has a wooden bob of mass 1 kg. It is struck by a bullet of mass kg moving with a speed of ms. The bullet gets embedded into the bob. The height to which the bob rises before swinging back is (use g = 10 m/s)
Answer: (A)
Solution
v = (0.01 × 200)/1.01 ≈ 1.98 m/s; h = v²/2g ≈ 0.20 m.
