What is the speed of a satellite orbiting at that height? Assume Mearth = 5.98 × 1024 kg.

Express your answer to two significant figures and include the appropriate units.

Answer #1

at what height above the earth is the free-fall acceleration 40
% of its value at the surface? assume rearth = 6.37 Ý 106 m.
What is the speed of a satellite orbiting at that height? Assume
Mearth = 5.98 Ý 1024 kg?

a-A scientist is on a high mountain top with a gravimeter that
records the free fall acceleration. The gravimeter reads that the
free fall acceleration is 0.00600 m/s2 less than the free fall
acceleration at sea level. What is the scientists altitude? Take
the radius of the earth to be 6.37×106 m and the mass of the earth
to be 5.98×1024 kg.
1.95×103 m
1.89×107 m
6.37×106 m
9.01×106 m
b-A rocket has a speed of 1.87×104 m/s as it...

A 4,000 kg satellite is traveling in a circular orbit 200 km
above the surface of the Earth. A 30.0 gram marble is dropped
inside the satellite. What is the force of gravity on the marble as
viewed by the observers on the Earth? (ME = 5.98 ×
1024 kg, RE = 6.37 × 106 m, G =
6.67 × 10−11 N·m2/kg2)
A 5,000 kg satellite is orbiting the Earth in a circular path.
The height of the satellite above...

(a) At what height above the earth is the acceleration due to
gravity 62% of its value at the surface?
(b) What is the speed of a satellite orbiting at that
height?
I got 1210.49km for question a by using the formula, but it is
wrong.

A projectile is launched vertically from the surface of the
earth with an initial speed ?0=6.23 km/s. The mass of the earth is
5.97×1024 kg, the radius of the earth is 6.37×106 m, and
?=6.674×10−11.
(a) What is the magnitude of the projectile's acceleration
1.63e3 km above the surface of the earth?
(b) At what height will the projectile stop and begin to fall
back to the surface of the earth?

NASA launches a satellite into orbit at a height above the
surface of the Earth equal to the Earth's mean radius. The mass of
the satellite is 830 kg. (Assume the Earth's mass is 5.97 1024 kg
and its radius is 6.38 106 m.) (a) How long, in hours, does it take
the satellite to go around the Earth once? h (b) What is the
orbital speed, in m/s, of the satellite? m/s (c) How much
gravitational force, in N,...

An earth satellite remains in orbit at a distance of 1.7100×104
km from the center of the earth. The Universal Gravitational
Constant is 6.67×10−11 N⋅m2/kg2 and the mass of the earth is
5.98×1024 kg. Part A What speed (in m/s) would the satellite have
to maintain? Express your answer using three significant figures.
