Suppose that you have a planet in a circular orbit about a star with the mass of the Sun. The orbital speed is 141 km/s. If you could increase the planet’s speed, what speed would you need to make it to escape the gravitational pull of its parent star?

- Astronomers discover an exoplanet (a planet of a star other than the Sun) that has an orbital period of 3.63 Earth years in its circular orbit around its sun, which is a star with a measured mass of 3.65×10^30 kg . Find the radius of the exoplanet's orbit. - In order better to map the surface features of the Moon, a 353 kg imaging satellite is put into circular orbit around the Moon at an altitude of 137 km....
Earth's orbital velocity is about 29 km/s and that maintains its nearly circular orbit. Suppose we had a spacecraft following Earth in its orbit, and we applied a rocket to speed it to 35 km/s. Assume the thrust is entirely in the plane of the orbit, so the spacecraft stays in the same plane as Earth's orbit. What happens?
Astronomers discover an exoplanet (a planet of a star other than the Sun) that has an orbital period of 3.17 Earth years in its circular orbit around its sun, which is a star with a measured mass of 3.99 × 1030 kg. Find the radius of the exoplanet\'s orbit.
Astronomers discover an exoplanet (a planet of a star other than the Sun) that has an orbital period of 3.01 Earth years in its circular orbit around its sun, which is a star with a measured mass of 3.11 × 1030 kg. Find the radius of the exoplanet\'s orbit.
A 507 kg satellite is in a circular orbit at an altitude of 754 km above a planet’s surface. This planet is similar to our Earth. Because of air friction, the satellite eventually is brought to the Earth’s surface, and it hits the Earth with a speed of 3 km/s. The radius of the planet is 7 × 106 m and its mass is 8 × 1024 kg. The gravitational constant is 6.67259 × 10−11 N m2 /kg2. How much...
A satellite is in orbit around a planet with orbital speed determine to be 4810 m/s. Find the escape velocity from the planet from this position of its orbit.
What is the orbital speed of a satelite in a circular orbit at 8, 129 kilometers above the Earth surface? Express your answer in km/s and round it to two decimals. Earth's mean radius is RE = 6.37 x100 m; Earth's mass is ME = 5.97x104kg. A What is the orbital period of a satelite in a circular orbit at 5,384 kilometers above the Earth surface? Express your answer in minutes (enter "min" for minutes) and round it to the...
