The discussion focuses on calculating the slide distance of a skier on a slope inclined at 4.7 degrees with an initial speed of 2.7 m/s and a coefficient of friction of 0.11. Participants emphasize the importance of determining the gravitational force component acting down the slope and the retarding force due to friction. The net force equation simplifies the problem, as mass cancels out, allowing the use of the formula v² = 2ad to find the distance before coming to rest.

LowlyPion said:What is the component of gravitational force on the skier that would induce the skier to continue down hill? What is the retarding force?. Using that find the rate of deceleration. That might be a good place to start then.
vysis said:thats the thing though... it doesn't give you the mass. It ONLY gives you the force of kinetic friction and the initial speed
