A boat moves at 5.00 m/s relative to the water. (You can neglect relativity at these slow speeds.)a. Find the boat’s speed relative to shore when it’s traveling downstream in a river with a 3.0 current.b. Find the boat’s speed relative to shore when it’s traveling upstream in a river with a 3.0 current. c. The boat travels 100 m downstream and then 100 m upstream, returning to its original point. Find the time for the round trip. t =
2. In the future, speeding tickets for spaceships will be issued based on the spaceship’s measured length. The Neptune 3000 spaceship has proper length 85 m .a. If the posted speed limit is 0.6c , will the Neptune 3000 spaceship be ticketed if space police measure its length as 75m ? y or N?

Text Problem (HELP)

(Comprehensive time value of money) Mr. Rambo, President of General Weapons, Inc., was pleased to hear that he had three offers from major defense companies for his latest missile firing automatic ejector. He will use a discount rate of 10 percent to evaluate each offer.
OfferI
\$1,200,000 now plus \$625,000 from the end of years 6 through 15. Also if the product goes over \$60 million in cumulative sales by the end of year 15, he will receive an additional \$3,000,000. Rambo thought there was an 80 percent probability this would happen.
Offer II
Thirty percent of the buyer’s gross margin for the next four years. The buyer in this case is Air Defense, Inc. (ADI). Its gross margin is 60 percent. Sales for year 1 are projected to be \$3.5 million and then grow by 35 percent per year. This amount is paid today and is not discounted.
Offer III
A trust fund would be set up for the next four years. At the end of that period, Rambo would receive the proceeds (and discount them back to the present at 10 percent). The trust fund called for semiannual payments for the next four years of \$110,000 (a total of \$220,000 per year). The payments would start immediately. Since the payments are coming at the beginning of each period instead of the end, this is an annuity due. To look up the future value of the annuity due in the tables, add 1 to n (16 1) and subtract 1 from the value in the table. Assume the annual interest rate on this annuity is 10 percent annually (5 percent semiannually). Determine the present value of the trust fund’s final value.
Required: Find the present value of each of the three offers and then indicate which one has the highest present value.
