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.
is the compression in the spring
Answer:
Average acceleration on first part of the chunk is given as
Average acceleration on second part of the chunk is given as
Explanation:
By momentum conservation along x direction we will have
so we have
also by energy conservation
by solving above equation we will have
Average acceleration on first part of the chunk is given as
Average acceleration on second part of the chunk is given as
