Problem

A 20 g20\,\text{g} bullet travelling horizontally at 300 m s−1300\,\text{m s}^{-1} embeds itself in a 1.98 kg1.98\,\text{kg} wooden block suspended by a light thread. Immediately after the impact the bullet-block system swings upward. Neglecting air resistance, to what maximum vertical height will the system rise? (a) 0.92 m0.92\,\text{m} (b) 1.84 m1.84\,\text{m} (c) 0.46 m0.46\,\text{m} (d) 0.23 m0.23\,\text{m}
