The velocity of block after the bullet emerges.
Given:
Mass of bullet is 23 gm.
Initial speed is 230m/sec
Mass of wood block is 2 kg.
At 170 m/sec bullet emerges.
Formula used:
According to law of conservation of momentum,
Here, m1and m2are the mass of bullet and block.
u1and u2are initial velocities of bullet and block.
v1and v2are the final velocities of bullet and block.
Calculation:
Applying the law conservation of momentum
Momentum of the system before collision = Momentum of the system after collision
Mass of bullet × initial velocity of bullet + mass of block × initial velocity of the block = mass of bullet × final velocity of the bullet + mass of the block × final velocity of the block
