Answer:22.22m/s
Explanation:
Answer: 22.22 m/s
Explanation:
Using the law of conservation of momentum:
Initial momentum of the system = final momentum of the system.
mu+m'u' = mv+m'v'
where u and u' are the initial velocities.
v and v' are the final velocities.
mass of bullet, m = 0.04 kg
mass of the block of wood, m' = 0.5 kg
initial velocity of bullet, u = 300 m/s
initial velocity of block, u' = 0
after collision, block and bullet would move together with velocity v
⇒0.04 kg × 300 m/s + 0 = 0.54 kg × v
⇒ v = 22.22 m/s
Thus, the bullet and the wood block move together as one object with the speed 22.2 m/s.
