Question
**Problem 1:** A 60.0 kg skier with an initial speed of 13 m/s coasts up a 2.50 m high rise as shown in the figure.

---

**Figure Explanation:**
The diagram illustrates a skier ascending a slope. Key elements include:
- An initial speed \( v_i = 13 \, \text{m/s} \).
- Initial kinetic energy labeled as \( \text{KE}_i \).
- An incline with an angle of \( 35^\circ \) leading up to a 2.5 m high rise where the final speed \( v_f \) is to be calculated.

---

**Task:** Find her final speed right at the top, in meters per second, given that the coefficient of friction between her skis and the snow is 0.39.

\[ v_f = \underline{\hspace{3cm}} \]

---

**Calculator Interface:**
- A numeric keypad is provided for calculations, including trigonometric functions such as sin(), cos(), tan(), and others like sinh(), cosh(), etc.
- Options for input in Degrees or Radians.

**Buttons:**
- Submit
- Hint
- Feedback
- I give up!
