Question
![**Problem Statement:**
A \(2.1 \times 10^3\)-kg car starts from rest at the top of a 5.5-m-long driveway that is inclined at \(15^\circ\) with the horizontal. If an average friction force of \(4.0 \times 10^3\) N impedes the motion, find the speed of the car at the bottom of the driveway.
\(\_\_\_\_\_\_\_\_\_\_\_) \, \text{m/s}\)
**Details:**
- Mass of the car: \(2.1 \times 10^3\) kg
- Length of the driveway: 5.5 m
- Incline angle: \(15^\circ\)
- Average friction force: \(4.0 \times 10^3\) N
**Instructions:**
- Use principles of energy conservation to find the speed of the car at the bottom of the incline.
- Consider gravitational potential energy at the top and kinetic energy at the bottom.
- Account for the work done against the friction force.
**Interactive Features:**
- Need Help? [Button] - Provides hints and guidance for solving.
- Read It [Button] - Offers detailed explanations and related examples.
- My Notes [Button] - Allows users to jot down thoughts or calculations.
