1. Consider a mechanical system without friction at which the total energy $E$ is the sum of kinetic energy $K$ and the potential energy $\varphi(r)$: $E = \frac{m}{2}\mathbf{v}(t) \cdot \mathbf{v}(t) + \varphi(r)$, where $m$ is the mass of the particle, and $\mathbf{r}(t)$ and $\mathbf{v}(t)$ are the position and velocity vectors of the particle as time $t$. (a) Using the fact that the total energy is conserved, derive the Newton's law: $\mathbf{F}(t) = m\frac{d\mathbf{v}(t)}{dt} = -\nabla\varphi(r)$. (b) The origin of the Cartesian coordinate is at the Earth's center. The moon is on the $z$-axis a fixed distance $R$ away (center-to-center separation). The tidal force exerted by the moon on a particle of mass $m$ at the Earth's surface is given by $\mathbf{F} = -\frac{GMm}{R^3}(x\hat{\mathbf{e}}_x + y\hat{\mathbf{e}}_y - 2z\hat{\mathbf{e}}_z)$, where $M$ is the mass of the moon and $G$ is the Newton's gravitational constant. Find the potential energy that yields this force.

An experimenter measures dx = 1.00 m, dy = 0.30 m, dz = 0.10 m, and dt = 6.0 ns as the space-time interval between two events. A second observer is moving at v = 0.500c in the x direction relative to the experimenter. Find the elements of the displacement measured by the second observer. Which of the following is correct? a) 1.50 m 0.12 m 0.30 m 0.10 m b) 1.20 m 0.15 m 0.30 m 0.10 m c) 0.12 m 0.15 m 0.30 m 0.10 m d) 2.00 m 0.15 m 0.30 m 1.50 m e) none of the above

A Workplace Incident Report: A workplace incident report is a form that is used to profile physical occurrences that impact an employee's productivity in the workplace. It includes workplace injuries, near misses, and accidents that have a negative impact on the employee (s) and the organization, in general. Usually, labor laws specify the kind of information that should be spelled out in a workplace incident report. This type of incident report may also highlight an employee's concerns with an organization's safety practices, security breaches, and workplace conduct. Examples of workplace incident reports include: • A report about sexual harassment or assault in the workplace. • A report about a fire incident that occurred within the office premises. Essential details in an effective incident report When designing an incident report form, make sure it covers as many details as possible. Successful incident reports include • The type of incident • The time and date of the incident • Names of the victims • Names of any witnesses • A general description of the situation • The sequence of events • The type of injuries • Required medical treatments • Video or photo evidence of the injury Task: Design your incident report forms by focusing on essential questions to gather facts about the situation: who, what, when, where, why, and how and write a detail injury report of an employee at your workplace one page in length.
