The majority of satellites orbiting the Earth do so at altitudes between 160 and 2,000 kilometers. Find the tangential velocity needed to keep a satellite in orbit at an altitude of 2000 km from the surface of the Earth. Answer this problem in the following two questions below.
Question 3 2 pts First, you want to find an equation for the velocity at which the centripetal force F. Mm is equal to the force of gravity F, = G ?נוז T Set Fc = F, and solve forv, what do you get? Ov Gm = O, GmM V Ov= Gm GM ขา
Question 4 2 pts Now that you have an equation for v, plug the following values in the right variables in the equation and calculate the velocity. Gravitational Constant = 6.7 * 10-11 mkg s 2 Mass of the Earth = 6 x 10^24 kg Radius of the Earth = 6,370 km Give your answer in units of km/s HINT: Add the Radius of the Earth and the altitude of the satellite to get i.e. r= Radius of the Earth + 2000 km (and don't forget to change the units to meters),
