23PRACTICE PROBLEM
A skier is skiing in the north direction at 5.0 m/s. The skier experiences a force of 3.0 N from the northwestern winds. The coefficient of kinetic friction is 0 while there exists static friction to prevent the skier from skidding sideways. Determine the skier's speed after skiing 50 m along with the wind. Consider the skier has a mass of 45 kg.
