If a spacecraft is headed for the outer solar system, it may require several gravitational slingshots with planets in the inner solar system. If a spacecraft undergoes a head-on slingshot with Venus as in Example 11.6, find the spacecrafts change in speed vS. Hint: Venuss orbital period is 1.94 107 s, and its average distance from the Sun is 1.08 1011 m.
Check Your Understanding By what factor must the radius change to reduce the orbital velocity of a satellite by one-half? By what factor would this change the period?
What is the orbital radius of an Earth satellite having a period of 1.00 h? (b) What is unreasonable about this result?
Check Your Understanding Assume you are in a spacecraft in orbit about the Sun at Earth’s orbit, but far away from Earth (so that it can be ignored). How could you redirect your tangential velocity to the radial direction such that you could then pass by Mars’s orbit? What would be required to change just the direction of the velocity?
Model the Moons orbit around the Earth as an ellipse with the Earth at one focus. The Moons farthest distance (apogee) from the center of the Earth is rA = 4.05 108 m, and its closest distance (perigee) is rP = 3.63 108 m. a. Calculate the semimajor axis of the Moons orbit. b. How far is the Earth from the center of the Moons elliptical orbit? c. Use a scale such as 1 cm 108 m to sketch the EarthMoon system at apogee and at perigee and the Moons orbit. (The semiminor axis of the Moons orbit is roughly b = 3.84 108 m.)

You wish to put a 1000.0 kg satellite into a circular orbit above the earth's surface with a period of 300.0min. The mass and radius of the earth is 5.972x10²⁴ kg and 6371km, respectively. What speed, distance from the earth's surface, and radial acceleration will it have?
What is the period of revolution of a satellite with mass m that orbits the earth in a circular path of radius 7940 km (about 1570 km above the surface of the earth)?
A satellite orbiting 42,164 km from the center of the Earth will revolve around the Earth at the same rate the Earth rotates, always staying above the same point on the ground if above the equator. Such a satellite is called “geosynchronous”. Q. If a satellite is moved to twice the distance from the center of the Earth, by what factor must its speed be changed to remain in a circular orbit?
Satellites that orbit at an altitude of 438 mil above the surface of earth are called sun-synchronous because the position directly below the satellite is always at the same time of day. Given their altitudes, what must be their periods of revolution?
