The shown system is on the Moon; gravity at the Moon's surface is 1.62 m/s². A=3 m; B=10 m; C=15 m. The shown particle exits the ramp with velocity of 8.4 m/s and $\theta$=55°. $\Box$ Determine the particle's height above ground when it has reached the indicated vertical plane that is coincident with the left side of the wall with height B. $\Box$ At the above condition, is the particle rising or falling?

Game Corporation produces and sells a single product. Data concerning that product appear below: Per Unit Selling price $240 Variable expenses 168 Contribution margin $72 Percentage 100% 70% 30% Fixed expenses are $301,000 per month. The company is currently selling 5,000 units per month. The marketing manager would like to introduce sales commissions as an incentive for the sales staff. The marketing manager has proposed a commission of $16 per unit. In exchange, the sales staff would accept an overall decrease in their salaries of $68,000 per month. The marketing manager predicts that introducing this sales incentive would increase monthly sales by 200 units. Required: a) Prepare a contribution margin format income statement using the original data. b) Prepare a contribution margin format income statement using the revised data. c) What should be the overall effect on the company's monthly net operating income of the proposed changes?

Question 2. [17 marks] For a particle of mass $m$, in the state $\Psi(x, t)$, the time-dependent Schrödinger equation is given by, $ih\frac{\partial \Psi}{\partial t} = -\frac{\hbar^2}{2m}\frac{\partial^2 \Psi}{\partial x^2} + V\Psi$. (a). Show that the rate of change of the probability density $|\Psi(x, t)|^2 = \Psi^*\Psi$ can be written as, $\frac{\partial}{\partial t}|\Psi|^2 = \frac{\partial}{\partial x}\left[\frac{ih}{2m}\left(\Psi^*\frac{\partial \Psi}{\partial x} - \frac{\partial \Psi^*}{\partial x}\Psi\right)\right].$ (b). Use part (a) to show that the rate of change of $<x>$, the expectation value of the position of the particle is $\frac{d<x>}{dt} = -\frac{ih}{m}\int \Psi^*\frac{\partial \Psi}{\partial x}dx.$ (c). Hence deduce the operator that represents the momentum in quantum mechanics.
