A single-stage rocket of mass 308 metric tons (not including fuel) carries a payload of 3150 kg to low-Earth orbit. The exhaust speed of the rockets cryogenic propellant is 3.20 103 m/s. a. If the speed of the rocket as it enters orbit is 8.00 km/s, what is the mass of propellant used during the rockets burn? b. The rocket is redesigned to boost its exhaust speed by a factor of two. What is the mass of propellant used in the redesigned rocket to carry the same payload to low-Earth orbit? c. Because the exhaust speed of the redesigned rocket is increased by a factor of two, why is the fuel consumption of the redesigned rocket not exactly half that of the original rocket?
Two stars each of one solar mass (= 2×1030 kg) are approaching each other for a head on collision. When they are a distance 109 km, their speeds are negligible. What is the speed with which they collide ? The radius of each star is 104 km. Assume the stars to remain undistorted until they collide. (Use the known value of G)
Two asteroids strike head-on: before the collision, asteroid A AmA = 7.5 * 10 3.3 kms 12 kgB Ge has velocity and asteroid B AmB = 1.45 * 10 1.4 kms 13 kgB A has velocity in the opposite direction. If the asteroids stick together, what is the velocity (magnitude and direction) of the new asteroid after the collision?
Use the definition of center of mass to answer the following questions: (a) The distance between the Earth and the Moon (center to center) is approximately 239,000 miles. How far is the center of mass of the Earth/Moon system from the center of the Earth? The mass of the Earth is 5.97 x 1024 kg and the mass of the Moon is 7.35 x 1022 kg. (b) The average distance between the Earth and the Sun (center to center) is approximately 93 million miles. How far is the center of mass of the Earth/Sun system from the center of the Sun? The mass of the Earth is 5.97 x 1024 kg and the mass of the Sun is 1.99 x 1030 kg.
A meteor of mass m is approaching earth as shown on the sketch. The distance h on the sketch below is called the impact parameter. The radius of the earth is Re = 6400km . The 6x1024 kg mass of the earth is me = Suppose the meteor has an initial speed of vo = 30km/s. Assume that the meteor started very far away from the earth. Suppose the meteor just passes earth at a distance of 2.5Re from the earth's center. You may ignore all other gravitational forces except the earth.

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.
Two spherical asteroids have the same radius R. Asteroid 1 has mass M and asteroid 2 has mass 2M. The two asteroids are released from rest with distance 10R between their centers. What is the speed of each asteroid just before they collide? Hint: You will need to use two conservation laws.

The Double Asteroid Redirection Test (DART) is a NASA mission that aims to redirect an asteroid by colliding with it. The target of DART is Dimorphos: a small asteroid that orbits Didymos, a larger asteroid, every 11.9 hours in a circular orbit. This binary system orbits the sun every 770 days in an elliptical orbit which crosses the orbits of both Earth and Mars. It is estimated that the impact of DART will change the velocity of Dimorphos by 0.4 mm s-1. A. How far would an object with a velocity of 0.4 mm s-1 travel in one year? You should take a year to be 365.25 days. B. The estimate of the change of velocity assumes that DART simply sticks to the surface of Dimorphos. Instead, suppose that the impact also causes a large amount of material to be thrown back out into space. How would this effect the estimate of the change of velocity?
During a solar eclipse, the Moon is positioned directly between Earth and the Sun. The masses of the Sun, Earth, and the Moon are 1.99 x 1030 kg, 5.98 × 1024 kg, and 7.36 x 1022 kg, respectively. The Moon's mean distance from Earth is 3.84 × 10 m, and Earth's mean distance from the Sun is 1.50 × 10'" is G = 6.67 x 10-1' N•m²/kg². m.
