- A new planet has a mass of 2.0x10^24 kg, a radius of 4.5x10^6m, and no atmosphere. A 100 kg space probe is to be launched vertically from its surface. If the probe is launched with an initial kinetic energy of 6.0 x 10^8 J, the what will be its velocity when it reaches 5.2x10^6m from the center of the new planet?arrow_forward55-56. Ganymede, one of Jupiter's moons, is the largest moon in our solar system. It has a mass of 1.48 × 1023 kg and a radius of 2.63 × 10 m. A 15.0 kg lunar rover is on Ganymede's surface. 55. As the rover orbits Ganymede, it is observed that during a particular segment of time, its speed decreases. During this segment of time, the work done by gravity on the rover is: a positive b) negative c zero d) more info is needed to determine 56. Find Ganymede's escape speed (the minimum launch speed from Ganymede's surface such that the projectile never falls back). a) 2.39 km/s b) 2.74 km/s c) 3.09 km/s d) 3.44 km/s e) 3.79 km/sarrow_forwardThis is a proportional reasoning calculation. You will want to set up equations, but mostly to look at how the orbital distance affects the orbital velocity, or to set up a ratio. (Once you know how it changes you'll have to multiply by the value at the surface to get an answer in m/s.) At the surface of the exoplanet G 9-40 b, the orbital velocity would be 1.21E+4 m/s. What would the orbital velocity be 11 radii above the surface? m/s. Note: If your answer requires scientific notation, remember that OWL uses "e" notation: 1.1 x 105 is 1.1e5 to OWL.arrow_forward
- The days on Mars and Earth are of nearly identical length. Earth's mass is 9.35 times Mars's mass, Earth's radius is 1.88 times Mars's radius, and Mars is on average 1.52 times farther away from the Sun than Earth is. The Martian year is 1.88 times longer than Earth's year. Assume that they are both uniform spheres and that their orbits about the Sun are circles. Estimate the ratio (Earth to Mars) of the following. (a) their spin angular momenta(b) their spin kinetic energies(c) their orbital angular momenta(d) their orbital kinetic energiesarrow_forwardA distant planet has a mass of 5.00 x 1023 kg and a radius of 6.00 x 106 m. Someone is standing on the surface of the planet and throws a rock straight up with initial speed of 7.0 m/s. What is the maximum hight reached by the rock above the point from where it was thrown?arrow_forwardYou are to help design a space probe that will land on Titan, a moon of Saturn. The probe also has to launch itself from the surface of that moon as it will come back to Earth with a rock sample. Mass of Titan: 1.35 x 1023 kg, Radius of Titan: 2.574 x 106 m. The sample will have a mass of 0.1 kg, and the rocket that will return it will have a mass of 200 kg (without the fuel). Your engine can fire with 18,800 N. - What is the gravitational acceleration on Titan in m/s2? - What will be the weight of the rocket in Newtons on Titan? - What velocity must the rocket reach in order to escape Titan? - How long would it take the engine to accelerate the rocket to escape velocity? (this assumes that the engine is accelerating the rocket only; we aren’t including the mass of the fuel) Using the information given (and what you figured out) use the following formula to find the total ∆v that your rocket can produce. - Is the ∆v enough to get from 0 m/s to escape velocity? - If it isn’t, plug in…arrow_forward
- 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. For this calculation, ignore any variation in gravity over the 500 km range of the debris. How high would this material go on earth if it were ejected with the same speed as on Io?arrow_forwardThe source of the Mississippi River is closer to the center of the Earth than is its outlet in Louisiana (because the Earth is fatter at the equator than at the poles).
