**Problem Statement:**

A girl on a skateboard (total mass of 33.6 kg) is moving at a speed of 12.0 m/s at the bottom of a long ramp. The ramp is inclined at 23° with respect to the horizontal. If she travels 14.1 m upward along the ramp before stopping, what is the net frictional force on her?

**Explanation:**

This physics problem involves kinetic and potential energy, as well as frictional force. The girl on the skateboard has an initial kinetic energy due to her speed and gains potential energy as she travels up the ramp. The objective is to calculate the frictional force that causes her to stop after traveling a certain distance. The problem requires understanding of energy conservation and forces on an inclined plane.
