It's your birthday, and to celebrate you're going to make your first bungee jump. You stand on a bridge 120 m above a raging river and attach a 30-m -long bungee cord to your harness. A bungee cord, for practical purposes, is just a long spring, and this cord has a spring constant of 45 N/m . Assume that your mass is 71 kg . After a long hesitation, you dive off the bridge.

Part A

How far are you above the water when the cord reaches its maximum elongation?

Express your answer with the appropriate units.

I need an equation for finding the veocity of water at the end of an incline.

• the velocity at the top is 0
• the incline is a right triangle with a hieght of 3000ft and a base of 9 miles
• the fluid is water
• the depth of the water is 3ft

Calculate the pH of the solution at each step after the addition of i) 0.00mL ii) 2.30 mL, iii) 10.0 and iv) 16.0 mL of 0.50 M HCL to 100.0 mL of 0.10 M NH₃ solution.

Your firm is evaluating a new $725,000 investment opportunity with a 16% required return. You expect to sell 3,500 units per year at $50 net cash flow each for the next 8 years. Suppose that after one year, you will know more about demand and be able to revise your estimate of future unit sales based on sales you observe for year 1. Further, suppose that the project can be dismantled and sold to net $650,000 at that time.

a. What is the minimum level of unit sales for year 1 below which would it make sense to abandon the project?

b. If the original expectation of 3,500 unit sales is the average of two equally likely outcomes (3,000 units or 4,000 units), what is the value of the project, including the option to abandon at the end of the first year?

Two Earth satellites, A and B, each of mass m, are to be launched into circular orbits about Earth's center. Satellite A is to orbit at an altitude of 7530 km. Satellite B is to orbit at an altitude of 24200 km. The radius of Earth R_Eis 6370 km. (a) What is the ratio of the potential energy of satellite B to that of satellite A, in orbit? (b) What is the ratio of the kinetic energy of satellite B to that of satellite A, in orbit? (c) Which satellite (answer A or B) has the greater total energy if each has a mass of 28.5 kg? (d) By how much?

you will select a somatoform or dissociative disorder discussed in Chapter 5, then discuss some of the possible causes and treatments that are available. Don't forget to reference your sources at the end of your initial post.

Crime rates are higher in certain areas of a city, frequently the central city. How do residents and businesses of these areas respond to these higher crime rates? What impact does this have on the entire city? Be sure to include the effect on tax revenue, city government spending, and any other effects.

Suppose that the first national bank currently holds a total of 45 million dollars in deposits from over 120,000 clients. At the same time, the total amount of loans people owe the bank is 18 million dollars, and the bank cannot legally issue more loans without attracting additional deposits. Assume that the bank currently has 3 million dollars in cash and 2 million dollars worth of securities invested in the financial market. The bank also owns some physical assets, such as its office building.

Suppose now someone saves another $52 into his checking account at the first national bank, what is the maximum amount of deposits that can be generated (including this initial deposit) by the fractional reserve banking system?

Round your answer to 2 digits after the decimal point.

• Explain decomposition and superposition of force vectors.
• Give applications of Newton's Laws of Motion in daily lives.

Section 6.9 of your textbook ("Debugging") lists three possibilities to consider if a function is not working.

Breaking a large program into smaller functions creates natural check points for debugging. If a function is not working, there are three possibilities to consider:
• There is something wrong with the arguments the function is getting; a precondition is violated.
• There is something wrong with the function; a postcondition is violated.
• There is something wrong with the return value or the way it is being used.

1. Describe each possibility in your own words.

2. Define "precondition" and "postcondition" as part of your description.

3. Create your own example of each possibility in Python code. List the code for each example, along with sample output from trying to run it.

Python: Using Inheritance to Create a Derived Class in Python

In this lab, you create a derived class from a base class, and then use the derived class in a Python program. The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status.

Instructions

1. Open the file named Motorcycle.py.
2. Create the Motorcycle class by deriving it from the Vehicle class. Use a public derivation.
3. In the Motorcycle class, create an attribute named sidecar.
4. Write a public set method to set the value for sidecar.
5. Write a public get method to retrieve the value of sidecar.
6. Write a public accelerate method. This method overrides the accelerate method inherited from the Vehicle class. Change the message in the accelerate method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast".
7. Open the file named MyMotorcycleClassProgram.py.
8. In the MyMotorcycleClassProgram, there are two Motorcycle objects named motorcycleOne and motorcycleTwo.
9. Set the sidecar value of motorcycleOne to true and the sidecar value of motorcycleTwo to false.
10. Set motorcycleOne’s maximum speed to 90 and motorcycleTwo’s maximum speed to 85.
11. Set motorcycleOne’s current speed to 65 and motorcycleTwo’s current speed to 60.
12. Accelerate motorcycleOne by 30 mph, and accelerate motorcycleTwo by 20 mph.
13. Print the current speed of motorcycleOne and motorcycleTwo.
14. Determine if motorcycleOne and motorcycleTwo have sidecars. If yes, display the following: "This motorcycle has a sidecar". If not, display the following: "This motorcycle does not have a sidecar".
15. Execute the program.

The ΔG°\' of the reaction is -7.050 kJ ·mol–1. Calculate the equilibrium constant for the reaction. (Assume a temperature of 25° C.What is ΔG at body temperature (37.0° C) if the concentration of A is 1.8 M and the concentration of B is 0.75 M?

Create properly formatted script file (Initials_Final_pb_02.m) that will prompt the user to input a 1-D array of numbers (positive, negative, zero) and then use loop and conditional statement to find the number of all non-zero elements in this array and their products

Do NOT use the built-in commands such as sum, prod, length, size, … etc.

-        Use proper names for input and output variables.

Use the following 3 vectors to test your function and include the results as a commented text at the end of your script file. [3 -1 0 -4 2], [10 -15 20 -15 0], [1 0 -2 5 -2 3]

Format the output using fprintf similar to the following:

There are 4 non-zero numbers and their product is 24
