Could someone please show me the work for these questions? The answers are already provided in bold.

I just do not know how to get these answers. When I tried, all I could do was assemble a Free-Body Diagram, and identity which forces are there in each problem. Now, I just need to know how to solve it from there. Please try and do 1 - 6 with work shown. Thank you for all you do!

AP Physics 1 Multi-Body Force Practice 1. Two objects, one with a mass of 5 kg, the other with a mass of 8 kg, are connected via a massless rope over a frictionless, massless pulley. What is the acceleration of the system when it is released from rest? 2.26 m/s? 2. From question 1, what is the tension in the rope? How does this compare to the force of gravity on the 5 kg and 8 kg masses? 60.30 N 3. A 10 kg box sits on a frictionless table. It is connected by a massless rope to a 4 kg block hanging off of the end of the table over a frictionless, massless pulley. What is the acceleration of the system when it is released from rest? 2.80 m/s? 4. If the 10 kg box in question 3 has a coefficient of kinetic friction between itself and the table of 0.25, what is the acceleration of the system? 1.05 m/s 5. What minimum coefficient of static friction is necessary for the 10 kg box to remain at rest in question 3? 0.40 6. A crate with a mass of 14 kg moves up a 30" incline at a constant speed. The crate is connected by a massless rope over a frictionless, massless pulley to a second 14 kg crate hanging over the "top" of the incline. Determine the coefficient of kinetic friction between the first crate and the incline. 0.58
