What's the escape velocity of a 100-kg satellite from the Moon's surface? Would the same satellite...
The escape speed from the Moon is much smaller than from Earth and is only 2.38 km/s. At what temperature would neon atoms with an atomic mass equal to 20.18 g/mol) have an average speed Vrms equal to the Moon's escape speed?
The escape speed from the Moon is much smaller than from Earth and is only 2.38 km/s. At what temperature would nitrogen molecules (with a molecular mass equal to 28.01 g/mol) have an average speed vms equal to the Moon's escape speed? K
A geosynchcronous satellite is one that stays above the same point on the Earth, that is it rotates with the same angular velocity than Earth. This is possible only if the satellite is above a point on the equator. Determine: a) The height above the Earth's surface such satellite must orbit? b) What is the satellite speed? c) If the satellite is orbiting 200 km above Earth, what is the satellite speed? ( Remember G=6.67x10-11 N m2/kg2, MEarth = 5.98x1024...
An 97 kg spacewalking astronaut pushes off a 685 kg satellite, exerting a 97 N force for the 0.5 s it takes him to straighten his arms. a. What impulse is delivered to the astronaut from the satellite? kg m/s b. What's the speed of the astronaut after he pushes off? (We'll call the astronaut and satellites initial velocity 0.) m/s c. What's the speed of the satellite after the astronaut pushes off? m/s d. How far apart are the...
Gravitational Fields: a) What is the escape velocity for a stationary object (of mass 100 kg) from a planet if an object dropped on its surface falls 5m in 1.4 seconds. (diameter of planet is 12,000 km) b) What is the objects velocity at a distance of 60, 000 km if the velocity is 1.2 times the escape velocity? Please show and explain as much work as possible. Thank you!

A satellite is at an altitude of 852 kilometers above the Earth's surface. The mass of Earth is 5.972 x 10^24 kg and the radius of Earth is 6.378 * 10^6 m. (1) What is the acceleration due to gravity in the orbit? (2) What is the orbital velocity and period of the orbit? (3) Derive the equation for the escape velocity of the orbit and provide the numerical value.
