A 30 kilogram block rests on a rough horizontal surface with μk = 0.20. It is connected by a mass less cord to a 10 kilogram block which is hanging freely from the edge of the table. The 30 kilogram block moves 5 meter after the system are released.

Evaluate what is the friction force?

Evaluate how much work is done on the surface by the 30 kg block?

Evaluate what the change in potential energy of the 10 kg block? Evaluate the speed of the system after it moves 5 m? Use energy methods only.
