SUMMARY
The coefficients of static and kinetic friction for a 1.55 kg book on a tabletop can be calculated using the forces required to initiate and maintain motion. It takes 2.50 N to start sliding the book, indicating the static friction force, and 1.50 N to keep it moving, indicating the kinetic friction force. The static friction coefficient (μs) is determined by the formula μs = F_static / F_normal, while the kinetic friction coefficient (μk) is μk = F_kinetic / F_normal. Given the normal force equals the weight of the book (approximately 15.19 N), the coefficients are μs = 0.164 and μk = 0.098.
