Question:

Cartons having a mass of 5 kg are required to move along the assembly line at a constant speed of 8 m/s. Determine the smallest radius of curvature for the conveyor so the cartons do not slip. The coefficients of static and kinetic friction between a carton and the conveyor are μ_s = 0.7 and μ_k = 0.5, respectively.
