Two blocks of masses M1=3.5 kg and M2=5.7 kg are at rest on a horizontal surface with a coefficient of friction uk = 0.12. You start them moving by pushing on block 1 with a force F1H = 33 N at an angel of theta = 42 degrees below the horizontal.
Draw free body diagrams for M1 and M2 and label each force and what type of force it is, if known, which object causes the force and which object feels the force.
Choose and label a coordinate system for your free body diagrams and apply N2L to the free body diagrams you have drawn in each direction.
Determine the magnitude of the kinetic friction force on each block.
In Example 5.7, we pushed on two blocks on a table. Suppose three blocks are in contact with one another on a frictionless, horizontal surface as shown in the figure below. A horizontal force F is applied to m₁. Take m₁ = 2.00 kg, m₂ = 3.00 kg, m3 = 5.10 kg, and
F = 16.0 N.

A 3.0-kg block sits on top of a 5.0-kg block which is on a horizontal surface. The 5.0-kg block is pulled to the right with a force F⃗ as shown in the figure . The coefficient of static friction between all surfaces is 0.56 and the kinetic coefficient is 0.39.What is the minimum value of F needed to move the two blocks? If the force is 10% greater than your answer for (a), what is the acceleration of each block?
