Explanation Given information: The mass of the planet is M . The minimum distance from the satellite to the center of the plant is r 0 . The maximum distance from the satellite to the center of the plant is r 1 . The angular momentum per unit mass of the satellite is h . The gravitation constant is G . Calculation: The expression for the initial velocity ( v 0 ) of the satellite as follows: v 0 = h r 0 The expression for the final velocity ( v 1 ) of the satellite as follows: v 1 = h r 1 The expression for the kinetic energy in A ( T A ) as follows: T A = 1 2 m v 0 2 The expression for the potential energy in A ( V A ) as follows: V A = − G M m r 0 Here, m is the mass of the satellite. The expression for the kinetic energy in B ( T B ) as follows: T B = 1 2 m v 1 2 The expression for the potential energy in B ( V B ) as follows: V B = − G M m r 1 The expression for the conservation of energy in the elliptical orbit as follows: T A + V A = T B + V B Substitute 1 2 m v 0 2 for T A , − G M m r 0 for V A , 1 2 m v 1 2 for T B and − G M m r 1 for V B . 1 2 m v 0 2 − G M m r 0 = 1 2 m v 1 2 − G M m r 1 v 0 2 2 − G M r 0 = 1 2 v 1 2 − G M r 1 v 0 2 − 2 G M r 0 = v 1 2 − 2 G M r 1 v 0 2 − v 1 2 = − 2 G M r 1 + 2 G M r 0 v 0 2 − v 1 2 = 2 G M ( 1 r 0 − 1 r 1 ) v 0 2 − v 1 2 = 2 G M ( r 1 − r 0 r 1 r 0 ) Substitute h r 0 for v 0 and h r 1 for v 1

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be create…

A spacecraft of mass m describes a circular orbit of radius ị around the earth. (a) Show that the additional energy AE that must be imparted to the spacecraft to transfer it to a circular orbit of larger radius r, is GMm(r2 – r¡) ΔΕ= where M is the mass of the earth. (b) Further show that if the transfer from one circular orbit to the other is executed by placing the space- craft on a transitional semielliptic path AB, the amounts of energy AE, and AEg which must be imparted at A and B are, respectively, proportional to r, and r¡: ΔΕΞ ΔΕΔΕ, ΔΕ

A space probe is to be placed in a circular orbit of radius 4o00 km about the planet Mars. As the probe reaches A, the point of its original trajectory closest to Mars, it is inserted into a first elliptic transfer orbit by reducing its speed. This orbit brings it to Point B with a much reduced velocity. There the probe is inserted into a second transfer orbit by further reducing its speed. Knowing that the mass of Mars is 0.1074 times the mass of the earth, that ra= 9004 km and rg= 180 004 km, and that the probe approaches A on a parabolic trajectory, determine the time needed for the space probe to travel from A to Bon its first transfer orbit. Approach trajectory Second transfer orbit В 4000 km First transfer orbit The time needed for the space probe to travel from A to B on its first transfer orbit is |h.
