You are on an interstellar mission from the Earth to the 8.7 light-years distant star Sirius. Your spaceship can travel with 70% the speed of light and has a cylindrical shape with a diameter of 6 m at the front surface and a length of 25 m. You have to cross the interstellar medium with an approximated density of 1 hydrogen atom/m3.
Calculate the time it takes your spaceship to reach Sirius.
Determine the mass of interstellar gas that collides with your spaceship during the mission.
Note: Use 1.673 × 10−27 kg as proton mass
A team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing
experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various
initial speeds. With what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to
the asteroid? Assume that the asteroid is approximately spherical, with an average density p
3.06 x 106 g/m³ and volume
V = 3.32 x 1012 m³. Recall that the universal gravitational constant is G :
6.67 x 10-11 N-m²/kg².
On Oct 31 2015, massive asteroid TB145 nicknamed "Spooky" passed near the Earth
vicinity. The measured diameter of the asteroid: 600meters, and its speed relative to
the Sun: 30.5 km/s.
(NOTE you are not given the parameters of collision, so they become important part
of the "worst case -best case scenario.") Treat the asteroid as spherical object with
the density of between 3g/cm³ to 4g/cm³. Treat an Earth's orbit around the Sun as a
perfect circle of radius =150 x 106 km. Take one year to be 365.24days.
Find the worst case scenario for the collision of such object with the Earth and find
the Maximum energy released in the completely inelastic collision of this object with
Earth. State your answers to the nearest mega-ton of TNT. (1 megaton of TNT=
4.184 X1015J).

- A satellite is floating in space. Solar wind sweeping past the satellite consists of a stream of particles, mainly hydrogen ions of mass 1.7×10−27 kg. There are about 0.5×105 ions per cubic meter, and their speed is 8.0×105 m/s. An `umbrella' attached to the satellite is slowly opened, such that the radius of the circular cross-section of the umbrella is changing with time as r(t)=bt2, where b=0.1 m/s2 is a constant (see the figure which shows the side and front views). What is the maximum change of momentum of the satellite due to the solar wind hitting this umbrella after a time of 10 seconds? Explain carefully why this is the maximum possible change.

Assume that the properties of a black hole depend only on the mass of the black hole. (a) One characteristic of a black hole is the area of its event horizon. Roughly speaking, the event horizon is the boundary of the black hole. Inside this boundary, the gravity is so strong that even light cannot emerge from the region enclosed by the boundary. We shall write A = G°c®m°. Use dimensional analysis to find a, ß , and y. (b) One quantities in thermodynamics is entropy (S), that measure the disorder of a system. The relationship between entropy S, energy E and temperature 0 of a system is given as follow: = .

- In the simple kinetic theory of a gas we discussed in class, the molecules are assumed to be point-like objects (without any volume) so that they rarely collide with one another. In reality, each molecule has a small volume and so there are collisions. Let's assume that a molecule is a hard sphere of radius r. Then the molecules will occasionally collide with each other. The average distance traveled between two successive collisions (called mean free path) is λ = V/(4π √2 r2N) where V is the volume of the gas containing N molecules. Calculate the mean free path of a H2 molecule in a hydrogen gas tank at STP.

(c) What is the work done if the atoms are moved from their equilibrium separation to a very large distance apart? (d) Is this a conservative force? If yes, show it! If no, explain.
