1.) Your friend is catching a falling basketball after it has passed through the basket. Her hands move straight down while catching the ball. Take that it takes about 0.10 s for the player to lower her hands to stop the ball. Assume the mass of the ball to be 0.60 kg, and that it has fallen a vertical distance of 1.2 m before reaching the player's hand. Determine the average force that her hands exert on the ball while catching it.

2.) On a frictionless horizontal air table, puck A (with mass 0.248kg ) is moving toward puck B (with mass 0.372kg ), which is initially at rest. After the collision, puck A has velocity 0.125m/s to the left, and puck B has velocity 0.653m/s to the right.

What was the speed vAi of puck A before the collision?

Calculate ?K, the change in the total kinetic energy of the system that occurs during the collision.

Johnny Dei inc. has a perpetual expected EBIT of $56,000,000 and is currently unlevered. The current required return on the firm's equity is 25%. The company has 2 million ordinary shares outstanding. The corporate tax rate is 27%. The firm is planning a recapitalization: it will issue $50,000,000 debt which it plans to keep constant perpetually and use the proceeds to buy back shares. The cost of debt is 7.25%.

1. What is the value of the company before the recapitalization is announced. What is the value of equity before the announcement? What is the price per share? 163,520,000 and 81.76
2. What is the value of the company after the recapitalization plan is announced (but not carried out yet)? What is the value of equity? What is the price per share? 88.51
3. How many shares needs to be repurchased? What is the value of shares after the repurchase? What is the price per share? 564,907.92 and 88.51

Many people find that they spend a lot of time on their smartphones each day without realizing how long they are scrolling through apps or playing games. A researcher wanted to test whether a mindfulness intervention would help people be more aware of how much time they spend on their phones, and if this might lead to decreased time spent on their phones each day. To perform this study, participants used an app that tracks phone usage in minutes the week before the mindfulness intervention, and the week after the intervention. Hypothetical data (in minutes) are provided in the table

1.) What are the populations in this study?

2.) What is the mean of the Distribution of Means of Difference Scores?

3.) Calculate the t-statistic at a p level of 0.05 and identify the critical t-values

4.) What is the 95 percent Confidence Interval?

Write a Java Program using the concept of objects and classes. Make sure you have two files Employee.java and EmployeeRunner.java. Use the template below for ease. (Please provide detailed explanation)

Class Employee

Class Variables:

Name

Work hour per week

Hourly payment

Class Methods:

- Get/Sets

- generateAnnualSalary(int:Duration of employment)

  annual salary = Hourly payment * Work hours per week * 50

If the employee is working for more than 5 years,

10% added bonus

-void displayAnnualSalary ( )

before and after tax considering there’s an effective 25% tax

Class EmployeeRunner

main method

            - Create an object of type Employee

            - Prompt the user to insert name, work hour per week, hourly payment and duration of

                employment in years

• Generate annual salary and display the before and after tax amount

Light Bulbs

A red light bulb has been flashing forever, according to a Poisson process with rate r. Similarly, a blue bulb has been flashing forever, according to an independent Poisson process with rate b. Let us fix t to be 12 o'clock.

1 What is the expected length of the interval that t belongs to? That is, find the expected length of the interval from the last event before t until the first event after t. Here, an event refers to either bulb flashing.

2 What is the probability that t belongs to an RR interval? (That is, the first event before, as well as the first event after time t, are both red flashes.)

3 What is the probability that between t and t+1, we have exactly two events: a red flash followed by a blue flash?

Zetatron is an​ all-equity firm with 270 million shares​ outstanding, which are currently trading for ​$16.62 per share. A month​ ago, Zetatron announced it will change its capital structure by borrowing ​$672 million in​ short-term debt, borrowing $ 812 million in​ long-term debt, and issuing ​$636 million of preferred stock. The ​$2 comma 120 million raised by these​ issues, plus another $ 75 million in cash that Zetatron already​ has, will be used to repurchase existing shares of stock. The transaction is scheduled to occur today. Assume perfect capital markets.

a. What is the market value balance sheet for Zetatron

i. Before this​ transaction?

ii. After the new securities are issued but before the share​ repurchase?

iii. After the share​ repurchase?

b. At the conclusion of this​ transaction, how many shares outstanding will Zetatron​ have, and what will the value of those shares​ be?

A health spa has advertised a weight reducing program and has claimed that the average participant in the program loses at least 20 pounds. A somewhat overweight executive is interested in the program but is skeptical about the claims and asks for some hard evidence. The spa allows him to select randomly the records of ten participants and record their weights before and after the program.

Test whether the average weight loss is at least 20 pounds.

Participant Before After

Ross Erickson 189 170

Josh Way 202 179

Laura Ewok 220 203

Luke Haas 207 192

Brandon Bott 194 172

etc. etc. etc.

State H0 and H1. You MUST show the five-step process for determining H0 and H1. (1 pt.) Be very careful how you handle the 20 pound difference! The variable with the larger numbers MUST be on the left.
