The PTA works for a skilled nursing facility and is frequently encouraged to bill patients for enough time so that they qualify for the highest Medicare payment allowed. The PT and PTA talk and decide that one of the patients is unable to work the amount of time that the manager is requesting. What are the ethical dilemmas presented in this scenario and what options do the PT and PTA have regarding this situation?

A small projectile of mass m is fired at an angle θ above the horizontal. The initial speed of the object is v0. Find the angular momentum of the projectile with respect to its initial position when the object is
a) at its initial location;
b) at the highest point of its trajectory;
c) about to strike the ground.
d) What is the source of the torque that changes the angular momentum of the object?

The great 18th-century economist Adam Smith wrote, “Little else is requisite to carry a state to the highest degree of opulence from the lowest barbarism but peace, easy taxes, and a tolerable administration of justice: all the rest being brought about by the natural course of things.” Explain how each of the three conditions Smith describes would promote economic growth.

A projectile is launched with an initial speed of 60 m/s at an angle of 35° above the horizontal. The projectile lands on a hillside 4.0 s later. Neglect air friction. (a) What is the projectile's velocity at the highest point of its trajectory? m/s (b) What is the straight-line distance from where the projectile was launched to where it hits its target? m

A certain elastic string has a spring constant of 18n/m, a relaxed length of 3 meters, and a mass of 20 grams. A 500 g mass is hung on a string and given a kinetic energy of 2J. While the mass is in oscillating, the string can be plucked and it will produce a sound. What is the highest and lowest frequency of sound which can be produced by plucking the string in this situation.

If a ball falls in vacuum from a certain height describe the total energy, the kinetic energy, and the potential energy during the fall. Describe the energy values at the initial point (highest point), at an intermediate point during the fall, and at the final point (ground level). Make sure to mention how the free fall in vacuum is different from a real life fall.
