A physics student on skis has a mass of m. This student is given a push on a frozen lake. The push gives the student an initial speed of 1.90 m/s. The coefficient of kinetic friction between the skis and the ice is 0.140. Use energy considerations to find the distance the student moves before he or she stops.
