QUESTION 4

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	$0.48	$0.51
Mileage in km/liter	35	28
Annual maintenance	$300	$200
Annual operating costs	$500	$500
Resale Value	2180	200

Enter the difference between the two options in AW:

On the moon the acceleration due to gravity is -1.6 m/s. a stone is dropped from a cliff on the moon and his the surface of the moon 40 seconds later. How do i find the position function of the stone?

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...

An object of 4 kg (assuming the acceleration of gravity g = 10 m / s2 ) suspended from a spring causes the spring to stretch 2 cm downwards. The object is moved 3 cm down from from its equilibrium position in the positive direction of movement, then it is released with speed zero initial. Assuming that there is no damping and that the object is under external force equal to: 20cos4(t) (N) a) Formulate the initial value problem that...
