Scientists want to place a 38000 kg satellite in orbit, Ask an Expert

Academics

Scientists want to place a 3800.0 kg satellite in orbit around Mars. They plan to have the satellite orbit at a speed of 2462.0 m/s in a perfectly circular orbit. Here is some information that may help solve this problem:

mmars = 6.4191 x 1023 kg

rmars = 3.397 x 106 m

G = 6.67428 x 10-11 N-m2/kg2

a) What radius should the satellite move at in its orbit? (Measured frrom the center of Mars.)

b) What is the force of attraction between Mars and the satellite?

c) What is the acceleration of the satellite in orbit?

d) What should the speed of the orbit be, if we want the satellite to take 8 times longer to complete one full revolution of its orbit?
