An object slides down a inclined surface in the presence of kinetic friction forces.
At the given inclination the kinetic friction force is found to be of magnitude 90 N.
Now, the angle that the surface makes with respect to the horizontal is increased and the object continues to slide down the surface.
WHAT will the magnitude of the new kinetic friction force present be?

  • Physics - ,

    Why are you avoiding analyzing friction force vs angle?

  • Physics - ,

    I haven't gotten to the chapter on friction yet, so I am totally clueless...I am still on kinematics and biomechanics right now.

  • Physics - ,

    So I am guessing kinetic friction forces is the same as friction problem before, so the answer would be greater than zero and less than 90 N?

  • Physics - ,

    yes.
