Speed Just After the Bullet Embeds
Difficulty: Easy · Topics: Momentum, Inelastic Collisions, Springs
O‘q tiqilgandan keyingi tezlik
A bullet of mass m = 0.02 kg moving at v = 300 m/s strikes and embeds in a block of mass M = 2.98 kg resting on a frictionless table. The block is attached to a wall by a light spring, which is still unstretched at the moment the bullet stops inside the block.

Find the speed of the block (with the bullet) immediately after the impact, in m/s.
v = 300 m/s tezlik bilan harakatlanayotgan massasi m = 0.02 kg bo‘lgan o‘q ishqalanishsiz stolda turgan massasi M = 2.98 kg bo‘lgan brusokka urilib, uning ichida qoladi. Brusok devorga yengil prujina bilan bog‘langan va o‘q brusok ichida to‘xtagan paytda prujina hali cho‘zilmagan.
