Question
#### Problem Statement
The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03.
1. **Calculate the minimum force F (in N) he must exert to get the block moving.**
- Minimum Force \(F\): \( \_\_\_\_ \, \text{N} \) ❌
2. **What is its acceleration (in m/s²) once it starts to move, if that force is maintained?**
- Acceleration: \( \_\_\_\_ \, \text{m/s}^2 \)
### Explanation of the Diagram
- The diagram shows a man pulling a block of ice with a rope.
- The block of ice weighs 49.0 kg.
- The angle between the rope and the horizontal surface is 25°.
### Coefficient Details
- **Static Friction Coefficient (μs):** 0.1
- **Kinetic Friction Coefficient (μk):** 0.03](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F086bbff5-cebe-457b-a380-688dda6bddc1%2F449f2a83-4d75-4eb2-b9d1-c2e3b4434e6f%2Fzjm5hu.png&w=3840&q=75)
