- 2. An asteroid of mass 1.3 x 1010 kg must be diverted 8.5 hours before striking the earth. How can this be done (in other words, how many 100 MT bombs are needed)? If needed, the radius of the Earth is 6.4 x 10° m and a 100 mega-ton (MT) explosion releases 4.1 x 10" J.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 kmkm (or even higher) above the surface. Io has a mass of 8.93×10^22kg 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? (RE = 6370 km, m_E=5.96×10^24kg) Express your answer with the appropriate units.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.

- 1) What is approximately the gravitational force of the sun on the planet mars? (RMs= 2.28 × 10®km, M, = 1.99 x 1030kg, MM =6.39 × 1023kg) %DWhat percent of Earth's acceleration due to gravity is the acceleration on Mars? Take G = 6.67 x 10^-11 N m^2/kg^2 and the mass of Mars 6.42 x 10^23 kg and its radius as 3400 km. (Answer should look like '55.5 %'.)The planet Earth, Jupiter, the Moon, and the Sun have the following values: mJ = 1.90x1027kg , mE = 5.97x1024kg , mM = 7.35x1022 kg , mS = 1.99x1030kg RJ = 6.99x107 m , RE = 6.37x106 m, RM = 1.74x106 m , RS = 6.96x108 m dEarth to Moon = 3.60x105 km , dEarth to Jupiter = 588x106m , dEarth to Sun = 150x106 km (a) Find the magnitude of the force of gravity acting on the planet Earth due to the planet Jupiter.

- 1.The planet Mercury has a mass of 3.30×1023 kilograms (kg) and a radius of 2440 kilometers (km). The universal gravitational constant is G = 6.67 × 10−11 Nm2/kg2. (a) If a is ball is launched upwards from the surface of Mercury with an initial speed of 2.15 kilometers per second (km/s), what height maximum height above the surface will it reach before falling back down? Give your answer in units of kilometers (km). Assume that the total mechanical energy of the ball is conserved. (b) What is the escape speed of Mercury? Give your answer in units km/s.The mean diameters of X and Y, two planets in the same solar system, are 6.5 x 10³ km and 1.2 x 104 km, respectively. The mass of x is 0.21 times the mass of Y. The value of g on Y is 8.1 m/s². (a) What is the ratio of the mean density of X to that of Y (Px / Py)? (b) What is the value of g on X? m/s² (c) The mass of Y is 4.372 x 1024 kg. What is the escape speed on X? m/sIn this problem, you will try to use proportionality, instead of direct calculation, to scale the Earth values of g and weight to those appropriate for another planet. Earth has a mass of 1 Earth mass, a radius of 1 Earth radius, and a surface gravity of 1g = 9.8 m / s². If your mass is 76 kg, you would weigh 744 Newtons. The mass of HD34445 f is 37.9 Earth masses, and it's radius is 6.859 Earth radii. Look at the surface gravity formula. Let's consider this in parts. If ONLY the mass changed, the surface gravity of HD34445 f would be a times that of Earth. If ONLY the radius changed, the surface gravity of HD34445 f would be times that of Earth. Combining the two factors, the surface gravity of must be times that of Earth. What would your weight be on HD34445 f, if your weight is 744 on Earth? Newtons. Note: If your answer requires scientific notation, remember that OWL uses "e" notation: 1.1 x 105 is 1.1e5 to OWL.
- A sphere of copper has a radius of 50.0 cm and a mass of 4690 kg. A sphere of unknown metal has a radius of 30.0 cm. The surfaces of the spheres are 20.0 cm apart. The force of gravitational attraction between the two spheres is 0.372 mN. What is the mass of the unknown metal?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.In this problem you will measure the gravitational constant in a series of “observational experiments,” making use of Newton’s law of gravitation and second law of motion as well as Kepler’s third law of planetary motion Suppose a rocket is launched as described in part (d) with an initial speed of vi = 494 m/s and attains a peak altitude of H = 12.7 km above the surface of Earth. Taking ME = 5.95×1024 kg and Ri = 6.41×106 m, what is the measured value of the gravitational constant, in units of N⋅m2/kg2?
