Equilibrium applications of Newton's laws of motion III

Click For Summary
SUMMARY

The discussion focuses on calculating the coefficient of kinetic friction for a toboggan sliding down an inclined plane at a constant velocity. The angle of the hill is 8.80 degrees. The user applies the formula for forces, using cosine and sine functions to determine the components of gravitational force acting on the toboggan. The key conclusion is that the frictional force must equal the component of gravitational force parallel to the incline to maintain constant velocity.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic trigonometry, specifically sine and cosine functions
  • Knowledge of frictional force and its calculation
  • Familiarity with inclined planes in physics
NEXT STEPS
  • Study the calculation of frictional forces on inclined planes

A toboggan slides down a hill and has a constant velocity. The angle of the hill is 8.80 with respect to the horizontal. What is the coefficient of kinetic frction between the surcae of the hill and the toboggan?

So i used the formula: sum of forces(x)= cos (8.80)=0.98823
Forces (y)= sin(8.80)=0.152986
Fk=MkFn

I'm not sure on what to do after this.
Thank you!

In the inclined plane, normal reaction Fn = mg*cosθ. Find the frictional force.
To have a constant velocity frictional force should be equal to...?
