Unreasonable Results Suppose you wish to shoot supplies straight up to astronauts in an orbit 36,000 km above the surface of the Earth. (a) At what velocity must the supplies be launched? (b) What is unreasonable about this velocity? (c) Is there a problem with the relative velocity between the supplies and the astronauts when the supplies reach their maximum height? (d) Is the premise unreasonable or is the available equation inapplicable? Explain your answer.

Please help with the solution to this problem using (km/s). I know we will use Hohmann Transfer and a combined plane change.
In the opening scene of the movie “Gravity” Dr Ryan Stone (Sandra Bullock) and Matt Kowalsky (George Clooney) are required to transit from the Hubble Space Telescope (Altitude 600 km, 28.5 degree inclination) to the International Space Station (Altitude 400 km, 51.6 degree inclination) using nothing but their Manned Maneuvering Units (MMU). An MMU has a delta V capability of about 30 m/s, and it would be impossible to perform this maneuver with so little delta V, but…
a.) How much delta V would be required for this maneuver?
b.) What if the maneuver did not require an inclination change (altitude change only?)
This time the quantities will be different, again randomly chosen by the computer. The mass will be much smaller for a different reason.
The shell is thin, but has a definite thickness. Calculate the (volume) density of the shell, in g/cm3. Here are the numbers:
R = 27 cm
M = 800 grams
thickness = 0.4 mm
In an open space, Arianna throws a tennis ball at an angle of 26∘ to the horizontal with an initial velocity of 78 feet per second. If the tennis ball is released at a height of 4 feet, the parametric equation would be x(t)=(78cos26∘)t, y(t)=−16t2+(78sin26∘)t+4.
After how many seconds does the tennis ball reach its maximum height? (Round your answer to the nearest tenth if necessary.)
