SUMMARY

The discussion centers on calculating the time a skier has to escape an avalanche on a 30-degree slope. Without friction, the skier has 6.4 seconds to move out of the way. When considering a coefficient of kinetic friction (Uk) of 0.1, the time increases to 7.03 seconds. The equation used for these calculations is Fk = UkN, which relates to the forces acting on the skier.

PREREQUISITES
  • Understanding of basic physics concepts, particularly forces and motion.
  • Familiarity with the coefficient of friction and its application in physics.
  • Knowledge of trigonometry, specifically how to calculate angles and slopes.
  • Ability to apply Newton's laws of motion in practical scenarios.
NEXT STEPS
  • Study the principles of Newton's laws of motion in detail.
  • Learn about the effects of friction on motion, specifically in inclined planes.
  • Explore advanced topics in kinematics and dynamics related to skiing and avalanche physics.
  • Investigate real-world applications of physics in avalanche safety and prevention techniques.
USEFUL FOR

This discussion is beneficial for physics students, educators, and outdoor enthusiasts interested in understanding the dynamics of skiing and avalanche safety.

an avalanche begins on a ski slope. the mountain is 30 degrees above horizontal. a skier is 100m downhill on path of avalanche
1. how much time does skier have to move out of way if no friction?
2. how much time does skier have if Uk is 0.1?

answer= 1. 6.4 s 2. 7.03 s


can someone please help me? the equation i am using is Fk = UkN

If this is homework I would advise taking it to the homework section of the site where you may get more help.
 
There's no friction in the first case. You've got to show some work as to how you might approach this problem.
