The diagram shows a system with an 8 kg mass on a table and a 2 kg mass hanging off the table.
If the system is frictionless, what is the acceleration of the system?

If the system is frictionless, what is the tension force on the string?

If the 8 kg mass in the diagram encounters 5 N of friction, how fast does the system accelerate?

If the 8 kg mass in the diagram above is encounters 5 N of friction, what is the value of the tension force on the string?
