1)
An astronaut is orbiting the Earth preparing to repair a
satellite. The satellite is in a circular orbit 600 km above the
Earth's surface, where the free-fall acceleration is 8.20
m/s2. Take the radius of the Earth as 6400 km.
a. Determine the speed of the
satellite. Express your answer in meters per
second.
b. Determine the time interval required to complete one orbit around the Earth. Express your answers in minutes
2)
The pilot of an airplane notes that the compass indicates a
heading due west. The airplane's speed relative to the air is 200
km/h. If there is a wind of 25.0km/h toward the north, find the
velocity of the airplane relative to the ground. Express your
answer in km/h

A geosynchcronous satellite is one that stays above the same point on the Earth, that is it rotates with the same angular velocity than Earth. This is possible only if the satellite is above a point on the equator. Determine: a) The height above the Earth's surface such satellite must orbit? b) What is the satellite speed? c) If the satellite is orbiting 200 km above Earth, what is the satellite speed? ( Remember G=6.67x10-11 N m2/kg2, MEarth = 5.98x1024...
