Solve the following problem three times, using: 1) forces, 2) work and energy, and 3) momentum and impulse. You can use kinematics for any of the three options, as necessary. Three blocks are connected as shown and are initially at rest. The pulley and string are massless and frictionless, but the table surface has friction. Block A has a mass of 7 kg, Block B has a mass of 0.9 kg, and Block C has a mass of 1.3 kg. If block C descends 4.5 m in 6 seconds, then what is the coefficient of friction between the table and Blocks A and B?
