Helmholtz Free Energy

The Helmholtz free energy is a thermodynamic potential used to calculate the measure of useful work from a closed system. This system is kept at constant temperature and volume. German physicist Hermann Helmholtz introduced this concept in 1882.

Two objects are connected by a light string passing over a light frictionless pulley as shown in Figure 2 ject of mass 5.00 kg is released from rest. Using the princi- ple of conservation of energy, (a) determine the speed of the 3.00-kg object just as the 5.00-kg object hits the ground.

Consider a light spring with k= 500 N/m that has been compressed 6 cm and placed horizontally on a frictionless table. The table top is located 0.75 m above the ground. A 300 g mass is placed in front of the spring and the spring is released. During the launch the mass travels a short distance along the table before flying off the edge. Using concepts of conservation of energy, determine the speed (in m/s) of the mass when it hits the ground. Enter the magnitude of the velocity below. You will turn in your written support for this question. In that written support, you must also determine the speed of the mass as it leaves the edge of the table top.

One end of a spring is attached to a solid wall while the other end just reaches to the edge of a horizontal, frictionless tabletop, which is a distance h above the floor.

The block is released, follows the trajectory shown, and strikes the floor a horizontal distance D from the edge of the table. Air resistance is negligible. Determine the time elapsed from the instant the block leaves the table to the instant it strikes the floor.
