78. In 1998, NASA launched Deep Space 1 (DS-1), a spacecraft that successfully flew by the asteroid named 1992 KD (which orbits the sun millions of miles from the earth). The propulsion system of DS-1 worked by ejecting high-speed argon ions out the rear of the engine. The en- gine slowly increased the velocity of DS-1 by about +9.0 m/s per day.

In a science-fiction TV show, the hero spent the entire 30 min fretting about running out offuel before he could pilot his spaceship back to base. Several times in the sequence thecamera cut from his worried face to the blasting rockets, to the fuel gauge, and back to hisworried expression as the engines roared and the fuel amount keeps decreasing. Whatshould he have done and what you would say about the writers of the show?
A planet is discovered orbiting a distant star. The mass of theplanet is 40 times the mass of the Earth, and its radius is one-tenththe Earth’s radius. If a 2400-kg rocket has an escape velocity v onthe Earth, how does the escape speed of a 1200-kg rocket on theplanet compare with v?
Voyager 1 and Voyager 2 surveyed the surface of Jupiter’s moon Io and photographed active volcanoes spewing liquid sulfur to heights of 70 km above the surface of this moon. Find the speed which the liquid sulfur left the volcano. Io’s mass is 8.9 x 10^(22 )kg, and its radius is 1820 km.
An object of mass m is launched from a planet of mass M and radius R. a)Derive and enter an expression for the minimum launch speed needed for the object to escape gravity, i.e. to be able to just reach r = ∞. b)Calculate this minimum launch speed (called the escape speed), in meters per second, for a planet of mass M = 6 × 1023 kg and R = 76 × 104 km.
Assume that an enough large asteroid (m = 30,000 kg) coming from the deep space (out of our galaxy so assume at infinity) with a velocity 15 km/s travels through our solar system. When it approaches the Earth, the scientists say that it would be attracted by the Earth and then would impact her. So we would like to research the impact of the asteroid if it hits to our planet. (The Earth radius: RE = 6.4x10° m, and the Earth mass: MĘ = 6.0x104 kg.) a) Write expressions for the initial mechanical energy of the asteroid and the final mechanical energy of the asteroid as it reaches the earth's surface. Do not plug in numbers for this first step. b) What would be the kinetic energy of the asteroid as it reaches the earth? c) What would be the speed of the asteroid as it reaches the earth? d) Now, assume that the asteroid makes a totally inelastic collision with the Earth, i.e., the asteroid embeds itself in the earth's surface. Find the final velocity of the earth, assuming it was at rest…
Three little ducks @ 4 4 crossing a highway at 0.5 mph. The third duckling sees a car coming at 20 mph, but the others are already in the middle of the road. You are the second duckling. What will happen to you and why??
One way astrophysicists have identifi ed “extrasolar” planets orbiting distant stars is by observing redshifts or blueshifts in the star’s spectrum due to the fact that he star and planet each revolve around their common center of mass. Consider a star the size of our sun (mass 1.99 x 1030 kg), with a planet the size of Jupiter(1.90 x 1027 kg) in a circular orbit of radius 7.79 x 1011 m and a period of 11.9 years. (a) Find the speed of the star revolving around the system’s center of mass. (b) Assume that Earth is in the planet’s orbital plane, so that at one point in its orbit the star is moving directly toward Earth, and at the opposite point it moves directly away from Earth. How much is 550-nm light redshifted and blueshifted at those two extreme points?
After consuming all of its nuclear fuel, a massive star can collapse to form a black hole, which is an immensely dense object whose escape speed is greater than the speed of light. Newton's law of universal gravitation still describes the froce that a black hole exerts on objects outside it. A spacecraft in the shape of a long cylinder has a length of 100m, and its mass with occupants is 1000kg. It has strayed too close to a black hole having a mass 100 times that of the sun. If the nose of the spacecraft points toward the center of the black hole, and if the distance between the nose of the spacecraft and the black hole's center is 10km (a) determine the total force on the spacecraft. (b) What is the difference in the force per kilogram of mass felt by the occupants in the nose of the ship versus those in the rear of the ship farthest from the black hole?
2. On their way back from the Moon, suppose that when the capsule holding Neil Armstrong, Buzz Aldrin, and Michael Collins was halfway between the Earth and the Moon (192000 km from the center of the Earth and the center of the Moon), its speed was 2 km/hr. Assuming they don't fire their thrusters, what is the speced of the capsule when reaches Earth? (If this seems the same as the previous problem, just with bigger numbers, you are missing a very important concept!)
Jupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 km (or even higher) above the surface. Io has a mass of 8.93×1022kg and a radius of 1821 km How high would this material go on earth if it were ejected with the same speed as on Io? (REarth = 6370 km, mEartg=5.96×1024kg) NOTE: Your answer suggests that you have assumed constant gravitational acceleration over the whole height of the ejected debris. Note that the gravitational field changes quite significantly over this height.
3. You are a person with incredible arm strength. You throw a ball of mass m = 2 kg horizontally with initialy velocity vo. (a) How quickly would you have to throw the ball so that the ball enters a perfectly circular orbit around Earth? (Assume your height is much less than Earth's radius). (b) How long would the ball take to complete one orbit? (c) Let's say you throw the ball with 1.2x the speed found in (a). What is the semi-major axis of the new elliptical orbit of the ball? (d) How long would it take for the ball to complete its new orbital jour- ney?
The radius Rh of a black hole is the radius of a mathematical sphere, called the event horizon, that is centered on the black hole. Information from events inside the event horizon cannot reach the outside world. According to Einstein's general theory of relativity, Rh = 2GM/c2, where M is the mass of the black hole and c is the speed of light. Suppose that you wish to study a black hole near it, at a radial distance of 48Rh. However, you do not want the difference in gravitational acceleration between your feet and your head to exceed 10 m/s2 when you are feet down (or head down) toward the black hole. (a) Take your height to be 1.5 m. What is the limit to the mass of the black hole you can tolerate at the given radial distance? Give the ratio of this mass to the mass MS of our Sun.
