In the desert there is a jail. After rebellion the single guard has been immobilized. He watched helplessly how prisoners left one by one with different speed in different directions. Later he free himself and took a motobike with extra seat. Now he can follow footprints and pick up one prisoner at a time and bring them back to jail. Each prisoner moves with constant individual speed v_i and left the jail at time t_i. In which order the guard should bring the prisoners back in order to minimize the time?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
