The distance from Mars to Neptune is 28.5 AU. how fast must a ship be going...
If Neptune originally formed at 20 AU and then migrated to its present distance of 30 AU, how much was Neptune's orbital speed reduced during the migration?
Neptune orbits the Sun with a period of 164.8 years. The average distance in kilometers (or the semi-major axis) of Neptune from the Sun is: a) 30 AU b) 4.5 × 109
The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...
The distance from the earth to the moon, Mars, and Jupiter is respectively 384x10Ⓡ, 55*10', and 588x10’meters. If a ship travels at a speed of 2x109 m/s, A) how long in seconds will it take to get to the A) Moon? B) Mars C)Jupiter You are near a lake. Wind speed is currently 8 m/s (-18 mph). There is smoke on the water. A) How far would the smoke travel in 30 minutes? B) The smoke came from some fire...
How fast is Mars moving in its orbit in km per second based on the following information: radius of Mars orbit around the sun is 142 million miles ; there are 687 Earth days in Mars's complete orbits.
How fast must an object be going if its rest length is 3.4 times as long as its observed length?
How fast would a roc falling from an 85 m high cliff on Mars be traveling when it hit the surface if gMars is 3.75 m/s', using vf-/2gh? m/s
11. How much energy from the Sun would the Curiosity Rover collect at Mars' average distance from the Sun of 1.52 AU, compared to how much that solar panel would collect at Earth? (Ignore any losses in energy due to the atmospheres of either body.) (The /is the division symbol.) a. 1/1.52 = 0.66) as much as received at Earth b. 1/(1.52 x 2) as much (= 0.33) as received at Earth c. 1/1.52 times as much (= 0.43) as...
Xena is going home from an interplanetary travel. Her ship is directed to Earth and is traveling at speed v. When she is at a distance L from Earth (in her reference frame) she sends a signal to her husband Yan to get the dinner ready. In her reference frame the dinner takes a time tD to cook. a) How far is she from Earth when she sends the signal in Yan’s reference frame? b) How long will it take...
QUESTION 26/27 To enter a port, a ship must navigate between the shore and the tip of a jetty. You must instruct the captain to take a trajectory such that the ship is always equally as far from the tip of the jetty A-(0,a) as from the closest point S on the shore y -0, as shown in the Figure. jetty a A - (0,a) shore (a) (2 marks) Let P - (x, y) be the position of the ship...
