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...
Calculate the speed of a satellite moving in a stable circular orbit about the Earth at a height of 2000 km from the surface of the earth (The mass of the earth is 5.97×1024 kg and the radius of the earth is 6.38×106 m).
1) Estimate how many days it would take to walk around the Earth (Earth's circumference, assuming that Earth is spherical), assuming 12 h walking per day at 4 km/h? (Radius of the Earth is 3,959 mile). A) 1200 B) 834 C) 1500 D) 700 E) 1000
A satellite is in a circular orbit around the Earth at an altitude of 2.52 106 m. (a) Find the period of the orbit. (Hint: Modify Kepler's third law: T2 =(4π^2/GMs)r^3 so it is suitable for objects orbiting the Earth rather than the Sun. The radius of the Earth is 6.38 106 m, and the mass of the Earth is 5.98 1024 kg.) _______________h (b) Find the speed of the satellite. _________km/s (c) Find the acceleration of the satellite....
Standing at the equator, you travel the circumference of the earth in one day as the earth rotates. The radius of the earth is 6371 km. A) What is your tangential velocity in m/s? B) What is your angular velocity in degrees/s? If the earth's rotation comes to a complete stop within 2 seconds, what is your angular acceleration in degrees/s2? (round all answers to 3 sig fig)
A satellite is in a circular orbit around the Earth at an altitude of 2.24 x 106 m. (a) Find the period of the orbit. (Hint: Modify Kepler's third law so it is suitable for objects orbiting the Earth rather than the Sun. The radius of the Earth is 6.38 x 106 m, and the mass of the Earth is 5.98 x 1024 kg.) h (b) Find the speed of the satellite. km/s (c) Find the acceleration of the satellite....
One of the primary goals of the Kepler space telescope is to search for Earth-like planets. Data gathered by the telescope indicates the existence of one such planet named Boralis orbiting a star 120 ly from our solar system. Consider an interstellar spaceship leaving Earth to travel to Boralis. The ship can reach 0.70c almost instantly and can also decelerate almost instantly. The ship is 175 m long in its reference frame. (a) What is the length of the moving...

piloting a state-of-the-art spaceship to α Centauri, which is a star about 4 lightyears away as measured from Earth. Your ship cruises at a speed of 0.6c. For this problem, you can assume that Earth and a Centauri are at rest with respect to each other. At your journey's midpoint, you decide to send a souvenir package to your folks back home. You launcha probe back to Earth at a speed of v 0.8c from your perspective. a. How long...
A UFO is observed directly above the earth moving at a constant velocity. An astronaut on the moon (3.8 108 m from earth) observes the UFO passing overhead 2.9 s later. From the UFO's reference frame, how long did it take to travel from the earth to the moon?
