QUESTION 4

  1. The gravity on Mars is 3.711 m/s². Since you came from the Moon previously, where gravity is 1.62 m/s², you have tiny leg muscles. Not only do you look funny but walking around is a struggle. You want a Mars hopper to take you around and there are two propellant options, hypergolic and LOX-hydrocarbon. You will use the vehicle on average 50,000 km per year, with a useful life of 3 years for the LOX engine and 4 years for the Hypergol. INTEREST is 10% per year. Other comparative information is as follows:

    LOX

    Hypergol

    Vehicle Cost

    $13,000

    $12,000

    Fuel per liter

The moon has a very low average atmospheric pressure of 3x10-15 bar (1 bar = 100,000 N/ m 2) and a gravity of 1.62 m/s².
The moon has a very low average atmospheric pressure of 3x10-15 bar (1 bar = 100,000 N/ m 2) and a gravity of 1.62 m/s². Assuming that the density of oil is 0.93 g/cm3, calculate the reading on a manometer of: (a) The atmospheric pressure of the moon in meters of oil (head) (b) The atmospheric pressure of the moon in meters of mercury (head), assuming mercury has a relative density of 13.6.

Mars Incorporated, makers of the M&M ́s, is considering a capital investment of $275,000 in new equipment. The equipment is expected to have a 5-year useful life with no salvage value. Depreciation is computed by the straight-line method. During the life of the investment, annual net income and cash inflows are expected to be $25,000 and $80,000, respectively. Mars's minimum required rate of return is 10%. The present value of 1 for 5 periods at 10% is .621 and the...
