Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

**Text Explanation:**

"Our skier is now racing down the \( y = 28.3 \, \text{m} \) height and angle \( \theta = 15.9^\circ \) hill again. This time there is friction on the hill. What is the coefficient of kinetic friction if her speed is now one half of what it would have been with no friction?"

**Diagram Explanation:**

The diagram shows a skier descending a triangular slope.

- The slope has a height denoted as \( y \), measuring 28.3 meters, represented by a vertical bracket and labeled with a red \( y \) on the left side.
- The angle of the slope, \( \theta \), is 15.9 degrees, indicated in red on the slope.
- The skier is illustrated at the top of the slope, moving downwards.

The problem involves calculating the coefficient of kinetic friction on the slope, given that the skier's speed with friction is half of what it would be without friction.
