What is the acceleration of gravity at a height of 6400 km above the Earth's surface?
At a height of 6400 km above the Earth's surface, the acceleration due to gravity can be calculated using the formula ( g' = g_0 \left( \frac{R}{R + h} \right)^2 ), where ( g_0 ) is the acceleration of gravity at the Earth's surface (approximately 9.81 m/s²), ( R ) is the Earth's radius (about 6400 km), and ( h ) is the height above the surface. Substituting the values, the effective gravity at this height is approximately 2.45 m/s². This demonstrates that gravity decreases with altitude, being significantly weaker at that height compared to the surface.
What is the speed of the earth to escape the sun's gravity?
The escape velocity from the Sun at the Earth's distance is about 42.1 km/s. This means that for an object to escape the Sun's gravity at this distance, it would need to travel at that speed. The Earth's orbital speed around the Sun is about 30 km/s, so it is not moving fast enough to escape the Sun's gravity.
What work is done in one complete orbit by the earth on a space station that orbits the earth at 375 km above the earth positive?
The work done by the Earth on the space station is zero since the force of gravity is perpendicular to the motion of the space station. This means that there is no displacement in the direction of the force, and thus no work is done.
Which planet would a person be the most likely to survive a 50 meter drop with no parachute?
None.On Mercury or Mars, which have the weakest gravity (acceleration = 3.8 m/s^2), you would still hit the ground at approx 20 m/s = 72 km/hour.
What is the speed of a spacecraft?
To orbit the Earth, a speed of 7.9 kilometers/second is required. To escape Earth's gravity, an initial speed of 11.2 kilometers/second is required. To travel to distant planets, the initial speed must be still higher.
