A rocket is launched off the surface of earth. If it has a speed of 2.62×103 m/s, what height above the surface will it reach? Take the radius of the earth to be 6.37×106 m and the mass of the earth to be 5.98×1024 kg.

A spy satellite is in circular orbit around Earth. It makes one revolution in 8.90 h. Mass of Earth is 5.974 × 1024 kg, radius of Earth is 6371 km and Gravitational constant G is = 6.674 × 10−11 N·m2/kg2. a. How high above Earth’s surface is the satellite? answer in km b. What is the satellite’s acceleration? answer in m/s^2

The moon has a mass of 7.35 x 1022 kg and a radius of 1.738 x 10° m. At what speed must a rocket be launched from the surface of the moon so as not to fall back to the moon?

A satellite is in a circular orbit about the earth (ME = 5.98×10245.98×1024 kg). The period of the satellite is 1.00×1041.00×104 s. What is the speed at which the satellite travels?(G = 6.67×10−116.67×10−11 N.m2/kg2)

An object is thrown upward with a speed of 15.2 m/s on the surface of planet X where the acceleration due to gravity is 1.8 m/s². What is the maximum height reached by the object? Answer: Check

On a planet whose radius is 1.80 × 104 km, the acceleration due to gravity is 16.5 m/s?. What is the mass of the planet?

Part A Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 2.1×104 m/s when at a distance of 2.6x1011 m from the center of the sun, what is its speed when at a distance of 4.0×1010 m. Express your answer in meters per second. Πνα ΑΣΦ m/s

One of your summer lunar space camp activities is to launch a 1210-kg rocket from the surface of the Moon. You are a serious space camper and you launch a serious rocket: it reaches an altitude of 229 km. What gain in gravitational potential energy does the launch accomplish? The mass and radius of the Moon are 7.36 × 1022 kg and 1740 km, respectively.

A 1000 kg satellite orbits the Earth at a distance of 4 times the Earth's radius measured from above the Earth's surface. The radius of the Earth is 6.38x 10°m and the mass of the Earth is 5.98x1024kg and the gravitational constant G= 6.67x10-11 Nm²/kg². What is the speed at which the satellite orbits the earth? 3540 m/s O 3780 m/s O 4110 m/s 3130 m/s 2920 m/s O 4370 m/s 3960 m/s O 3350 m/s

Scientists have discovered a distant planet with a mass of 8.2x1023 kg. The planet has a small moon that orbits with a period of 6 hours and 36 minutes. Use only this information (and the value of G) to calculate the radius of the moon's orbit (in units of 106 m).
