Answer:
15 m/s to the right
Explanation:
Let's say right is positive and left is negative.
Momentum is conserved:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(6.0 kg) (25.0 m/s) + (15 kg) (0 m/s) = (6.0 kg) (-12.5 m/s) + (15 kg) v₂
v₂ = 15 m/s
Answer:
is the compression in the spring
Explanation:
Given:
- mass of the bullet,

- mass of block,

- stiffness constant of the spring,

- initial velocity of the spring just before it hits the block,

<u>Now since the bullet-mass gets embed into the block, we apply the conservation of momentum as:</u>



Now this kinetic energy of the combined mass gets converted into potential energy of the spring.
