The projectile motion equation is s(t)=-16t^2+vt+h where s(t) represents the distance or height of an object at time t, v represents the initial speed of the object in ft/s, and h is the initial height of the object, measured in feet.

If an object is starting at rest, then v=0 (such as for a penny being dropped from a building). If the object is starting from the ground, h=0. The baseball or cannonball situations, each have an initial velocity. For example, the initial velocity of the baseball is based on the speed at which the ball comes at you (the speed of the pitch).

Come up with a situation that you can model with this equation. Describe the situation and tell us what v and h are. Fill in the values so that you have a quadratic equation. If you do research to find initial velocities, include the links to the websites where you found that information. If you would like to make up your own numbers as well, you can (be creative)!

Once you have your equation, find the maximum height as well as the time it takes to reach that maximum. Then use your equation to find when the object hits the ground (i.e. the x-intercepts).

Finally, use those three points as well as the initial height to sketch a graph. You can take a photo of it and include the image or use an online graphing calculator and take a screenshot if that is easier.

After reading the below posting, how might this all tie into SMART goals, task types and running a better meeting?

The information from income statements and balance sheets can encourage better

management practices in the following manner:

1. The amount of debt in the balance sheet is a critical factor in deterring the "going concern" of a business. If the long-term debt is very high, then the overall cost of capital for the company as such and projects in general will increase which can be corrected by the management.

2. The Current assets and the current liabilities give a clear picture of the working capital scenario and the liquidity situation of the business. This information will be captured in the balance sheet. Higher current assets are always preferred, and management can take corrective steps if required to better manage the liquidity.

3. The Shareholders equity when seen with the total number of shares outstanding of the business help the financial managers in calculating the book value of the business. From this, the investors can check whether the current share price is overvalued or undervalued.

4. The Net profit is the most important figure in the income statement which provides information about the profitability of the business and how the business is performing when compared to its peers in the industry.

5. The Revenues or the top line help analyses when the profits are generated due to the increase in revenue or better operational efficiencies.

6.It is proposed to study the entry of an aircraft launched torpedo into seawater. The full-size prototype torpedo is 2.44 m in length and enters at 100 m/s into seawater which has a kinematic viscosity, ν = 1.17 x 10-6 m2/s (see the table in the front cover of your textbook). A model test is proposed where the length of the model torpedo is 0.537 m in length. The desire is to predict the force on the prototype torpedo upon entry into the water, using the measured force in the model study.

a.Assuming F = f(ρ, μ, V, L, g) determine the relevant dimensionless parameters for this flow phenomenon. Use ρ, V and L as the repeating variables in your analysis. V is the entry velocity, L is the length of the torpedo and g is the acceleration of gravity.

b.Assuming the dimensionless parameter containing the viscosity is not important at these conditions determine the necessary launch velocity in the model study and the force on the prototype if the measured model force is 9 N. (Assume g is the same for both the model and prototype. Also assume seawater is used in the model study.)

c.Now, assume the dimensionless parameter containing the viscosity is important. Can the fluid used in the model study be the same as the prototype fluid (seawater)? Explain. If not, can you find a fluid for the model study such that full similitude is achieved between the model and prototype? What fluid?

Access Part V of the IG009 Assessment Scenarios document. You are the senior controller for Healing Touch, a manufacturer of high-quality products designed to help support healthy spines. Its newest product offering is a massage chair and you plan to perform a variance analysis of the chairs manufactured this month to determine if the standards are being met. Once you have completed the analysis, you plan to show it to the production department manager and ask for an explanation of any variances that you believe should be examined. Assuming that Healing Touch manufactured 500 massage chairs this month, use the data contained in Part V of the Assessment Scenarios document to calculate all materials and labor variances in Excel (or other spreadsheet software). Be sure to include price, quantity, wage rate, and labor efficiency variances.

You have created a galvanic cell in order to perform the following UNBALANCED reaction. First, balance the reaction. Br- + Ag+ → Br2 + Ag

Part 1: You look up the appropriate reduction potentials for this reaction, and you find the following: Half Reaction Eo (V) Br2 + 2e- → 2Br- 1.11 Ag+ + e- → Ag 0.77 What is the voltage of the reaction given in the introduction? Br- + Ag+ → Br2 + Ag

Part 2: We will use this voltage to calculate K and ΔGo. From your balanced reaction, what number will you use for n?

Part 3: In order to calculate K from ΔG, we must select the appropriate value of R. The question, then, is what units will ΔGo have after the calculation. Note that Faraday's constant (F) has a value of 96500 C/mol, E has units of V, n has units of moles, and 1 V = 1 J/C. Which of the following is the correct value for R? A 0.00831 kJ/(mol*K) B 0.0821 L*atm/(mol*K) C 8.31 J/(mol*K)

Part 4: What is the value of ΔGo for the reaction determined in part 1 (in J/mol)?

Part 5: If the above reaction is carried out at 298 K, what is the value of K?

• E₁ = 1.15 eV
• E₂ = 1.1 eV

4) For E = 1.1 eV, suppose the probability density at some position,x, outside the well is P(x) and the probability density 1 nm farther from the well is P(x+1 nm). What is the ratio, P(x+1 nm)/P(x), of these two probailities?

Ratio =

5) If we squeeze the well (decrease L), the energies of the states will increase. What is the limiting value κ_limit of an energy state's κ as its energy approaches the top of the well in nm^-1(i.e., as E → 1.2 eV).

Two events are observed by inertial observer Stampy to occur a spatial distance of 15 c·s apart with the spatial coordinate of the second larger than the spatial coordinate of the first. Stampy also determines that the second event occurred 17 s after the first. According to inertial observer Philip moving along Stampy’s +x axis at unknown velocity v, the second event occurs 10 s after the first. (1 c·s = 1 light-second = unit of distance.)

a) Given Philip measures the spatial coordinate of the second event to be larger than the first, determine v.

b) How far apart spatially (in c·s) do the two events occur according to Philip?

c) Does there exist an inertial reference frame v < c in which the second event can occur before the first? Briefly explain in one sentence at most.
d) Inertial observer Kenny observes the proper time between the two events. How fast along Stampy’s +x axis does Kenny move?

(Note: Each part of this question can be done independently of any other. In part a, depending on how you solve it, you might obtain two answers as solutions of a quadratic, but one of them is extraneous, because it violates the premise in part a. If you are careful, you can avoid the quadratic at the outset, but it requires you to solve part b first.)
