Two blocks, connected by a string which can be considered massless, are wrapped around a frictionless, massless pulley as shown below (in effect, the mass of the puliey and string can be considered negligible as compared to that of the blocks). If the bottom block is pulled with a force of 39.2N it is found that each block slides at a constant velocity. If the coefficient of kinetic friction is equal for all surfaces, determine such coefficient. The masses of block 1 and blocks 2 are 4kg and 2kg respectively. m2

Question
**Physics Problem on Kinetic Friction and Pulley Systems** *Problem Statement:* Consider two blocks connected by a string, which is assumed to be massless, wrapped around a frictionless, massless pulley. This setup is shown in the accompanying diagram. The mass of the pulley and string is considered negligible compared to that of the blocks. When the bottom block is subjected to a horizontal pulling force of 39.2 N, both blocks are observed to slide at a constant velocity. This implies that the net force acting on the system is zero, and all frictional forces are balanced by the applied force. Your task is to determine the coefficient of kinetic friction, assuming that it is uniform for all contact surfaces in the system. The given masses are as follows: - Mass of block 1 (m₁): 4 kg - Mass of block 2 (m₂): 2 kg *Diagram Explanation:* In the diagram, a pulley is mounted on a vertical wall. A string, which loops around the pulley, connects two blocks. Block 1 (m₁) is on the surface beneath the pulley, and block 2 (m₂) sits directly atop block 1. The pulley is depicted to the left side of the blocks, illustrating a typical setup in classical mechanics problems. *Note:* Approach this problem by considering all forces acting upon the blocks, including gravitational and frictional forces, and apply Newton's laws of motion to solve for the coefficient of kinetic friction.
