Homework Help Overview

The problem involves a skier descending a slope inclined at 30 degrees, with a specified coefficient of kinetic friction. Participants are tasked with drawing a force diagram and calculating the skier's acceleration.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to describe the forces acting on the skier in their force diagram, including normal force, gravitational components, and friction. Some participants question the net force acting on the skier and seek hints for further clarification.

Discussion Status

The discussion is ongoing, with participants exploring the accuracy of the force diagram and the concept of net force. Guidance has been offered regarding the vector sum of forces, but no consensus has been reached on the next steps.

Contextual Notes

Participants are working within the constraints of a homework assignment, which may limit the information they can share or the methods they can use.

Homework Statement


skier decends a slope of 30 degrees. Assume the coefficient of kinetic friction is 0.1

draw a force diagram
find his acceleration

Homework Equations





The Attempt at a Solution

force diagram i have normal force up, cos(theta)mg down, Force friction left and sin(theta)mg right?
 
Physics news on Phys.org
So what's the net force on the skier?
 
idk give me a hint please
 
and am i correct in drawing my force diagram

The net force is the vector sum of all the forces as shown in your force diagram. Your force diagram sounds correct from the description you gave, but a drawing would be better.
