be applied to it so that it leaves earth in a
parabolic orbit?
Round your answer to two digits after the
decimal place.
Me = 6x1024kg
6400km
Re
G = 6.673x10-"Nm²kg
Hint: Do you remember the derivation of
escape velocity?

7.) A sateltle orbits at a height of 6,000 km above the earth’s surface. REarth = 6.38 × 106 m, mEarth = 5.98 × 1024 kg. What is the magnitude of the gravitational acceleration g at this height, in m/s2? Use G = 6.67 × 10-11 N·m2/kg2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
Kepler’s Law relates the period T ( in a sec) of a satellite to the distance from the center of the earth r (in m) to some physical constants as shown: T2 = (2π/ G ME) r3 Where G = Universal Constant of Gravitation and ME is the mass of the earth. A stationary satellite is one that circles the earth in a circular orbit but stays exactly above the same spot on the earth. Calculate the distance above the earth in m for this “geo-synchronous satellite” to orbit, then convert that height to miles.

1. Gravity: A satellite circles the earth three times per day (it has an 8-hour period). Given Mearth = 5.98x1024 kg, rearth = 6.38x10° km, and G=6.67x10" Nm²/kg², and assuming the orbit is circular, a. Find the radius of the orbit, how many earth radii is it? b. What is the speed of the satellite (in km/s)? c. What is the acceleration due to the Earth's gravity at that radius, i.e. what is "g" at the satellite radius? How much stronger is g at the Earth's surface (what is g/g.t_sat)?
