A 2,200-kg car is moving down a road with a slope (grade) of 14% at a constant speed of 11 m/s. What is the direction and magnitude of the frictional force?
(define positive in the forward direction, i.e., down the slope)?

A 2,282-kg car is moving up a road with a slope (grade) of 10% at a constant speed of 12 m/s. What is the direction and magnitude of the frictional force?
(define positive in the forward direction, i.e., up the slope)?

Q2. Read the paragraph and answer the following (write it down on a paper)

"A bottled water company want to change how they are selling their product by the traditional method. They want from their customers to have the option to buy from them directly instead of buying their products through Supermarkets or grocery stores".

- What are the options the company can take to allow customers to buy directly from them?

- How can they create a value to attract more customers to buy directly from them?

- Is there any advantage of using Technological factors to achieve their goal?

You are purchasing a 2015 Chrysler 200 for $19,400, with 20% down. The balance will be financed at 7.6% over seven years with monthly payments. Find:

Monthly payment

Total interest charges

Interest in month three

How much interest is saved if you increase monthly payments by $50?

Five years later you sell for $5,000, and you must pay off the remaining loan balance when sold. What is your net cash position after selling?

Note: average auto depreciation is almost 50% in three years; Chrysler has poorest resale of all domestic manufacturers.

A few hints:

Be exact with your PMT. Don't round. Over many time periods, it results in significant imprecision.

For monthly interest, #1 -- find PMT, #2 -- find interest by multiplying principal x rate x time (1/12 of a year). #3 -- subtract interest from payment. #4 -- difference is principal reduction for the 1st month. #5 -- subtract #4 from original principal balance, then repeat step 2.

Use a finance calculator or Excel. No tables. Avoid modeling...imprecision and errors are common.

• What are variable costs? How are they broken down? • Explain the concept of payback period. • Discuss the concept of fixed costs. How are they different from variable costs? • Give three reasons to keep good records every day.

Why does a frisbee behave differently when thrown upside down?

You are considering purchasing a car with a sticker price of $36,270 (nonnegotiable with no down payment required). You wish to make monthly payments for six years and the most you can afford to pay is $600 a month. Your local bank/credit union has agreed to loan you the money at a 4.39% annual interest rate. Create an amortization table reporting the beginning/ending loan balance, total payment, and portion of payment going to interest and principal. Create a IF statement that answers the question of whether you can afford the loan. What is your monthly loan payment and what is your total interest paid on the loan?

Justify the statement: ‘Coronavirus global lock down affect atmosphere of environment’.

The price of the typical MP3 player (such as the iPod) has been going down in the past 10 years. What could explain this consistent drop in the price of MP3 players? Use the model for the long-run competitive firm to illustrate your answer (hint: you need two diagrams here: one showing the LAC for the typical firm, and another showing the long -run supply curve for the industry.)

under what circumstances can the supply curve shift up or down

Explain how top-down and bottom-up processes guide attention.
