A satellite of mass 190 kg is placed into Earth orbit at a height of 150 km above the surface.

(a) Assuming a circular orbit, how long does the satellite take to complete one orbit? 1.47 Correct: Your answer is correct. h

(b) What is the satellite's speed? 7815 Correct: Your answer is correct. m/s

(c) Starting from the satellite on the Earth's surface, what is the minimum energy input necessary to place this satellite in orbit? Ignore air resistance but include the effect of the planet's daily rotation. 5.78e+09 Incorrect: Your answer is incorrect.

The satellite has some initial kinetic energy on the surface of the Earth because of the Earth's rotation. What is the total energy of the satellite when it is orbit? J
