the coefficient of static friction between a sled and snow is 0.16, with a coefficient of kinetic friction of 0.12. A 280-N girl sits on a 180-N sled with Murphy, a companion that weighs 45-N. How much force directed parallel to the horizontal surface is required to start the sled in motion? How much force is required to keep the sled in motion? 25) today, you are purchasing 100 shares of stock on margin. the purchase price per share is $35. the initial margin requirement is 70 percent and the maintenance margin is 30 percent. the call money rate is 4.5 percent and you are charged 1.6 percent over that rate. what will your rate of return be if you sell your shares one year from now for $37 a share? ignore dividends. Jati Sdn. Bhd. plans to create a new department for research and development (R & D). The department is fully operational 5 years from now. An old store will be refurbished for the R & D activities. The company needs around RM 100,000 in year 4 and RM 150,000 in year 5 for refurbishment works and procurement of the tools. A fund is created to finance the project and the company will start to save some money for every three months for 5 years starting 3 months from now. Calculate the total saving for every three months if the interest given is 6% per year compounded for every quarterly basis? You wish to contribute a $48,000 deposit towards a margin loan from the Notional Investment Bank Ltd.

Assuming you have borrowed the maximum allowed amount, what is the buffer amount, assuming no change in the underlying portfolio value?d) Assuming a decline in the value of your portfolio by 10%, what is the dollar value of your portfolio?e) Would this decline in your portfolio value trigger a margin call? Wind Farms (Example) Consider a location where the wind blows at 15 m/s. 2 options with two rows of turbines perpendicular to the prevailing winds all at same hub height are available: 1. 1st row - 12 turbines, each with a rotor dia. of 60 m, with Prated = 1.5 MW. 2nd row 500 m behind the 1st - 12 turbines, each with 60 m rotor dia. Prated = 1.5 MW 2. 1st row - 15 turbines, each with a rotor dia. of 50 m, with Prated = 1 MW. 2nd row 600 m behind the 1st - 12 turbines, each with 60 m rotor dia. Prated = 1.5 MW In each case, consider a = 0.1, G = 8/9, and operation at sub-rated wind speed, Psub-rated = Prated (Vsubrated/Vrated) For each of the 2 options, determine: a) The total power production in MW. b) The installation cost, if the turbines cost $800/installed kW. c) The total annual O&M cost, if annual O&M costs are 7% of installed cost + $10/MWh for maintenance. d) The annual net income (= Sales - annual O&M), if sale of energy is $30/MWh Which of the following is likely to happen when the actual rate of inflation is higher than the expected rate of inflation?Group of answer choicesLenders will tend to gain relative to borrowers.The purchasing power of money will increase.Borrowers will tend to gain at the expense of lenders.The actual real interest rate will be higher than the expected real interest rate. the assembly department started the month with 24,100 units in its beginning work in process inventory. an additional 309,100 units were transferred in from the prior department during the month to begin processing in the assembly department. there were 29,100 units in the ending work in process inventory of the assembly department. how many units were transferred to the next processing department during the month? multiple choice 333,200 362,300 304,100 314,100 Calculate the spot rates. b.

Assume that one-year zero-coupon yield is 3.5%. Create a complete yield curve using an appropriate technique. 3. Using the term structure model with mean-reverting interest rate create an inverted yield curve showing 1, 2, 3, 4, and 5-year yields. You need to set appropriate parameters to achieve this.

Question 4.Consider the following scenario:Abbie's Paper Mill and Boris's Tire Factory are both polluting the Arkansas River with 100 tons of minerals per month(each-for 200 tons per month cumulatively.Assume there are no other producers polluting the Arkansas River.The State Government aims to reduce total mineral pollution to 150 tons/month to avoid water eutrophication.The two firms have different costs in reducing mineral pollution:$100/ton of minerals for Abbie's Paper Mill and $200/ton of minerals for Boris's Tire Factory.The State Goverument is considering two options:strict command-and-control regulation and pollution permits."Clearly state which of the two options is more effective.Assume that for the command-and-control regulation,both firms have to equally account for pollution reduction (split the difference between current pollution and desired pollution target equally).Please describe clearly how much each option is worth in $.That is,conduct the cost-benefit analysis from the perspective of the government.
