A 3.00 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0380 m. The spring has force constant 900 N/m. The coefficient of kinetic friction between the floor and the block is 0.400. The block and spring are released from rest and the block slides along the floor.

Transcribed Image Text:### Exercise 7.24 - Enhanced - with Feedback
A 3.00 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0380 m. The spring has a force constant of 900 N/m. The coefficient of kinetic friction between the floor and the block is 0.400. The block and spring are released from rest and the block slides along the floor.

Transcribed Image Text:### Physics Problem: Speed of a Moving Block
**Part A**
**Problem Statement:**
What is the speed of the block when it has moved a distance of 0.0150 meters from its initial position? (At this point, the spring is compressed by 0.0230 meters.)
**Instructions:**
Express your answer with the appropriate units.
**Given Attempt:**
\( v = 0.63 \frac{m}{s^2} \)
**Feedback:**
- The given answer is incorrect.
- Remaining attempts: 4
