Question

A 25g bullet moving with an initial speed of 400 m/s is fired into and passes through a 1.05 kg block of wood. The block, initially at rest, acquires a speed of 7.0 m/s. Find the speed of the bullet after it goes through the block.

Step 1

- Mass of the bullet, \( m_1 = 25 \, \text{g} = 0.025 \, \text{kg} \) - Initial speed of the bullet, \( v_{1i} = 400 \, \text{m/s} \) - Mass of the block, \( m_2 = 1.05 \, \text{kg} \) - Initial speed of the block, \( v_{2i} = 0 \, \text{m/s} \) - Final Show more…
