Challenge Problems
Push your limits with challenges.
Question 1
A 75 kg person stands on an incline of 30 degrees with respect to the horizontal. Calculate both the static friction force and kinetic friction force if the coefficient of friction is 0.5.
💡 Hint: Remember to calculate both the forces acting due to gravity.
Question 2
Discuss how the coefficient of friction would change if the surfaces of contact were more textured versus smoother.
💡 Hint: Consider real-life examples of materials and their friction in daily activities.
