A rocket travels horizontally, close to the earth. The centripetal acceleration of the rocket is the earth's gravity (9.8 m/s2). If the earth's radius is 6.3 x 106 m and we neglect air resistance, how fast must the rocket be going to keep a constant height above the earth's surface?

You have a rocket of mass 2350 kg. How much work does the force of gravity do on the rocket if it moves from Earth's surface to 3.0 times the Earth's radius away? Be careful to use the definition of work that accounts for a force that changes based on location! J G = 6.67 x 10-11 m3/kg/s2 MEarth = 5.97 x 1024 kg REarth = 6.37 x 106 m What is the change in gravitational potential energy as the...

An object is dropped from rest from a height 7 × 10^6 m above the surface of the earth. If there is no air resistance, what is its speed when it strikes the earth? The acceleration of gravity is 9.81 m/s2 and the radius of the Earth is 6.37 × 10^6 m. Answer in units of km/s.

A rocket is launched from the Earth’s surface. Unfortunately, the engineers have miscalculated and the rocket runs out of fuel when its height is exactly one earth radii above the earth’s surface. The rocket immediately falls from rest back to toward the surface. Ignore friction and air resistance in your calculations.

The acceleration due to gravity, g, is constant at sea level on the Earth's surface. However, the acceleration decreases as an object moves away from the Earth's surface due to the increase in distance from the center of the Earth. Derive an expression for the acceleration due to gravity at a distance h above the surface of the Earth, 9h.
