Transcribed Image Text:**Problem Statement:**
A 172 N sled is pulled up a 31-degree slope at a constant speed by a force of 156 N. What is the coefficient of kinetic friction between sled and slope?
---
This problem involves calculating the coefficient of kinetic friction for a sled on an inclined plane. The key details are:
- The weight of the sled is 172 N.
- The incline is 31 degrees.
- The pulling force is 156 N.
The goal is to determine the coefficient of kinetic friction, which is a value that represents the frictional force resisting the motion of the sled relative to the normal force.
To solve this, use the following physics principles:
1. **Calculate the normal force**: It is affected by the gravitational force acting perpendicular to the slope.
2. **Calculate the gravitational component parallel to the slope**: This is the portion of gravity pulling the sled down the slope.
3. **Determine the frictional force**: Since the sled moves at constant speed, the net force parallel to the slope is zero.
**Note**: There are no graphs or diagrams included with this problem.
Expert Solution
