The discussion revolves around a physics problem involving a skier on an inclined slope, where the goal is to determine the distance the skier will slide before coming to a stop. The scenario includes parameters such as the angle of inclination, initial speed, and coefficient of friction.
Some participants have offered guidance on how to approach the problem by suggesting that the mass may not be necessary for calculating the net force and deceleration. The discussion reflects a mix of attempts to clarify the problem and explore different interpretations of the given information.
There is an acknowledgment that the problem does not provide the mass of the skier, which raises questions about how to proceed with the calculations. Participants are considering the implications of this missing information on their approach to the problem.

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
