Consider a spacecraft in an elliptical orbit around the earth. At the low point, or perigee, of its orbit, it is 300 km above the earth's surface; at the high point, or apogee, it is 4500 km above the earth's surface. What is the period of the spacecraft's orbit? Using conservation of angular momentum, find the ratio of the spacecraft's speed at perigee to its speed at apogee. Using conservation of energy, find the speed at perigee and the speed at apogee. It is necessary to have the spacecraft escape from the earth completely. If the spacecraft's rockets are fired at perigee, by how much would the speed have to be increased to achieve this? What if the rockets were fired at apogee?

A space of mass 120 kg is going to use a planet for a gravitational assist- that is, use the planet's gravity to change its direction of travel without expending any fuel. It is initially moving at a velocity of 280 m/s and at an angle of theta initial = 53 degrees, at a distance of 11500 km from the center of the planet. Given an expression for the angular momentum of the spacecraft using the coordinate system specified in terms of m, r0, v0, theta initial, and vector units i, j, k If the spaceship whips around the planet to the other side so that the angle is theta 35 and is moving at 95 m/s, how far, in kilometers, from the planet is it?

A satellite describes an elliptic orbit about a planet of mass m . Denoting by r0 and r1 , respectively, the minimum and maximum values of the distance r from the satellite to the center of the planet, derive the relationwhere h is the angular momentum per unit mass of the satellite.
