Three blocks are connected together 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 5 kg, Block B has a mass of 0.8 kg, and Block C has a mass of 1.1 kg. If block C descends 3.75 m in 5 seconds, what is the coefficient of friction between the blocks A and B and the table? Solve this problem three times, using the three main concepts we've covered in class: 1) forces, 2) work and energy, and 3) momentum and impulse. You can use kinematics for any of the three options, as necessary.

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
