A bullet is fired into a long wooden Block with velocity 4 cm/s. when ...
Given Information:
- Initial velocity of bullet: 4 cm/s
- Distance traveled by bullet inside the block: 12 cm
- Speed lost by the bullet inside the block: 2/3
Explanation:
- Initial Analysis:
- Let us assume the length of the block is L cm.
- The bullet enters the block with a velocity of 4 cm/s and travels a distance of 12 cm.
- Velocity of the Bullet Inside the Block:
- After traveling 12 cm inside the block, the bullet loses 2/3 of its speed.
- This means the bullet's speed reduces to 4 cm/s * (1 - 2/3) = 4 cm/s * 1/3 = 4/3 cm/s.
- Time Taken Inside the Block:
- The time taken by the bullet to travel 12 cm inside the block can be calculated using the formula:
time = distance / velocity = 12 cm / (4/3) cm/s = 9 seconds.
- Final Analysis:
- Since the bullet comes out of the block with zero speed, it means the total distance traveled by the bullet inside the block is equal to the length of the block.
- Using the time calculated earlier, we can find the length of the block:
L = velocity * time = 4 cm/s * 9 s = 36 cm.
- Conclusion:
- The length of the block is 36 cm.
- Initial velocity of bullet: 4 cm/s
- Distance traveled by bullet inside the block: 12 cm
- Speed lost by the bullet inside the block: 2/3
Explanation:
- Initial Analysis:
- Let us assume the length of the block is L cm.
- The bullet enters the block with a velocity of 4 cm/s and travels a distance of 12 cm.
- Velocity of the Bullet Inside the Block:
- After traveling 12 cm inside the block, the bullet loses 2/3 of its speed.
- This means the bullet's speed reduces to 4 cm/s * (1 - 2/3) = 4 cm/s * 1/3 = 4/3 cm/s.
- Time Taken Inside the Block:
- The time taken by the bullet to travel 12 cm inside the block can be calculated using the formula:
time = distance / velocity = 12 cm / (4/3) cm/s = 9 seconds.
- Final Analysis:
- Since the bullet comes out of the block with zero speed, it means the total distance traveled by the bullet inside the block is equal to the length of the block.
- Using the time calculated earlier, we can find the length of the block:
L = velocity * time = 4 cm/s * 9 s = 36 cm.
- Conclusion:
- The length of the block is 36 cm.
