Consider four different oscillating systems, indexed using i = 1 , 2 , 3 , 4 . Each system consists of a block of mass m i moving at speed v i on a frictionless surface while attached to an ideal, horizontally fixed spring with a force constant of k i . Let x denote the displacement of the block from its equilibrium position. Order the systems from largest total mechanical energy to smallest.

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.
