An artificial satellite is in a circular orbit d=470.0 km above
the surface of a planet of radius r=3.95×10^3 km. The
period of revolution of the satellite around the planet is T=1.15
hours. What is the average density of the planet?
An Earth satellite moves in a circular orbit 924 km above
Earth's surface with a period of 103.3 min. What are
(a) the speed and (b) the
magnitude of the centripetal acceleration of the satellite?
A 425 kg satellite is in a circular orbit at an altitude of 400
km above the Earth's surface. Because of air friction, the
satellite eventually falls to the Earth's surface, where it hits
the ground with a speed of 2.00 km/s. How much energy was
transformed to internal energy by means of friction?

A satellite is launched into an orbit at an altitude 200 km
above the surface. Onboard is an exquisitely sensitive atomic clock
that is synchronized with an identical clock on Earth. After
orbiting for one year, the satellite is captured, returned to
Earth, and the clocks compared. What will be the shift in time
between the two clocks?
We want to place a satellite moving in a circular orbit 500 km above the earth's surface in a circular orbit 1000 km above the earth's surface. To do this, first give the satellite a speed increase of ikenv while it is in the 1st green orbit and place it in the 2nd yellow elliptical orbit, and then, when the elliptical orbit reaches a distance of 1000 km from the ground, it gives it a second Δv 'velocity and allows...
A 2690-kg spacecraft is in a circular orbit 2320 km above the
surface of Mars.
How much work must the spacecraft engines perform to move the
spacecraft to a circular orbit that is 4730 km above the
surface?

Comet Halley approaches the Sun to within 0.570 AU, and its orbital
period is 75.6 yr. 1 AU = 1.50 x 1011 m). How far from the Sun will

A satellite moves in orbit about the Earth at a height of 9500
km above Earth's surface. Find a) the velocity of the satellite; b)
it's period of rotation; c) the magnitude of the Earth's
gravitational force on the satellite if it's mass is 2500 kg; d) if
the satellite's velocity is increased by 20% at what height must it
now orbit the Earth?
Explain D step by step please.
A satellite of mass 100 kg is in circular orbit about planet
Uzaz, which has a mass M and radius R, at an altitude (above the
surface) h.
(a) (2 points) Express the linear speed v of
the satellite in terms of the given variables and the universal
gravitational constant.
(b) (3 points) Suppose that if h = 1 × 104 km,
the period of the orbit is T = 11 hours. If Uzaz has a mass of 7.0

Assume that a rocket is in Earth’s orbit at 450 km above the
surface.
a) Calculate the orbital velocity in km/s
b) Calculate the escape velocity from said orbit and g in this
orbit
A 4600 kg lunar lander is in orbit 40 km above the surface of
the moon. It needs to move out to a 280 km high orbit in order to
link up with the mother ship that will take the astronauts home.
How much work must the thrusters do?
